orthodontic extrusion vs crown lengthening

Prosthetic rehabilitation. 0000032395 00000 n Esthetic crown lengthening for maxillary anterior teeth. Bruhnke M, Bitter K, Beuer F, Bse MWH, Neumeyer S, Naumann M. Quintessence Int. Histology after a gingivectomy, showed the re-establish of the junctional attachment at 12 days with hemidesmosome33 and a functional arrangement with collagen maturation after 3-5 weeks.34 However, when a flap is elevated and an osseous surgery is performed, the healing process is longer and collagen fiber bundles will reform only after 2 months and approximately 5-6 months for the collagen fiber bundles to arrange perpendicular to the root surface.35 Bone resorption following surgical crown lengthening provides supracrestal tooth structure for the attachment of connective tissue, leading to reestablishment of the biologic width depending on the amount of scaling and root planning. 0000032316 00000 n The crown is the portion of the tooth visible above the gum line. Is the opposing occlusion on a natural tooth or a prosthesis? Types of bridges may vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Please enable it to take advantage of the complete set of features! The osseous recontouring results in recapturing the normal form of the alveolar process at a more apical level (Fig. Surgical extrusion is one of the options to obtain the ferrule effect. 12 Based on the accumulated information, it is evident that contraindications will include 7: Deep caries or fracture requiring excessive bone removal Unaesthetic post-surgical outcomes data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAKAAAAB4CAYAAAB1ovlvAAAAAXNSR0IArs4c6QAAHCNJREFUeF7tnQd0VFXXht+ZSQ8lIYFEqmBoiiAiTYpSBGkWQJrto9mooYOACooURanSBQQ . Close evaluation of the tooth in question is required. 2023 Newcom Media Inc. All Rights Reserved. Etiology and Diagnosis: We best serve our patients when we approach the consideration for functional crown lengthening beyond the viewpoint of the individual tooth in question and evaluate all of the patients presenting factors. Subsequently, knowing the gingival zenith position (GZP) of each maxillary anterior tooth from the vertical bisected midline (VBM) as well as the gingival zenith level (GZL) of the lateral incisors can help facilitate a reference point during esthetic periodontal plastic surgical procedures. Alveolar bone anatomic profiles as measured from dry Clinical ramifications. -, Clark D., Levin L. In the dental implant era, why do we still bother saving teeth? Root structure supported by sound bone greater than the mass of the completed restoration is a favorable indication for crown lengthening, which is the less-aggressive treatment choice. The purpose of the treatment is for creating or exposing more tooth structure so a restoration can be placed. First, each tooth is different and requires a specific treatment recommendation. Lets face it. Crown lengthening is typically done by A gum specialist (also known as a periodontist) typically performs crown lengthening, though an oral surgeon or general dentist may, as well. Aug 2013;84(8):1126-1133. The goal would always be long-term predictability of the outcome, and it is important to understand the overall risks of the patient. If the tooth has not had a lot of restorative dentistry and there appears to be a significant amount of healthy tooth structure remaining that crown lengthening alone will allow access to restore the tooth, functional crown lengthening is an excellent option. 0000014707 00000 n government site. Dent. People with gummy smiles have normal-sized teeth; they just appear smaller in crown lengthening before and after pictures due to excess gum tissue that partially covers them. A healthcare provider will evaluate X-ray images of your teeth and ask about your medical history, especially the medications you're taking. It allows dental surgeons to perform restorative procedures, like fitting crowns or bridges or filling cavities. J. Endod. Annals of periodontology / the American Academy of Periodontology. This complex includes the sulcus, the junctional epithelial attachment, and dentogingival fibers. Zirconia Crowns: The Facts that You Need to Know. Ochsenbein C, Ross S.

A collective review of current concepts. Variations of these components can make a smile attractive or unattractive. 1998 Oct;18(5):424-33. Gary M. Radz, DDS, is associate clinical professor at the University of Colorado School of Dentistry in Denver, Colorado, and a dentist in private practice in Denver, Colorado. Many factors seem to contribute to the maintenance of tooth structure gained through surgical crown lengthening procedures. Intentional Replantation as Treatment of Extrusive Luxation: A Case Report. What is the caries risk and history for the patient? If the tooth has had extensive restorative treatment, had a root canal, and/or extensive decay, we know that the tooth is probably structurally compromised. This brings up two important variableswhat is the condition of the periodontium and what does the opposing occlusion look like? 0000045826 00000 n Bone Grafting / Tissue Regeneration Materials. While achieving a 2-mm ferrule on the buccal and lingual aspects of the tooth has long been considered sufficient to satisfy the functional demands placed on the restored tooth, the literature suggests the height of the interproximal ferrule plays a role in resistance and retention form, especially when the restoration involves multiple teeth as in a fixed partial denture. Measuring periodontal biologic distances: Transperiodontal vs transsurgical. Formation of the biologic width following crown lengthening in nonhuman primates.

Crown lengthening interproximally often results in a loss of papilla height and the unfortunate consequence of open cervical embrasures, also undesirable in the esthetic zone. A Case Report. I believe there are a couple of major considerations. See this image and copyright information in PMC. For patients who already suffer from an altered passive eruption, otherwise known as a gummy smile, crown lengthening is a good choice. Does the professional have a known history with the patient, and after communicating the risks and alternative, what does the patient want? To provide magic numbers for the clinician, mathematic theorems as the golden proportion and golden percentage have been proposed. doi: 10.5125/jkaoms.2019.45.5.254. Garber DA, Salama MA. Crown lengthening is a procedure in which the gum and bone tissue surrounding the teeth is altered to expose additional healthy tooth material, effectively lengthening them. Expand 10 The treatment of traumatized permanent anterior teeth: case report & literature review. Along with options, the risks and benefits of each option need to be clear so that the patient can make an educated and informed decision. Chu SJ, Tan JH, Stappert CF, Tarnow DP. Friedman N. The apically repositioned flap. Developing coronal tooth tissue with a minimally invasive surgical extrusion technique. In addition to the esthetic and periodontal factors, the biomechanical risk factors must be measured. The average dimensions for the biological width were found to be: for the sulcus 0.69 mm (range 0.4-1.09mm), the epithelial attachment 0.97 mm (range 0.44-1.56mm) and the connective tissue attachment 1.07 mm (range 0.69-1.04mm). Orthognatic procedures may also be suggested as a treatment option for repositioning of the maxilla. Before It is also useful for enhancing maxillary anterior esthetics. A Systematic Review and Exploratory Randomized Trial. 2023 Jan;129(1):61-68. doi: 10.1016/j.prosdent.2022.08.033. Orthodontic extrusion of tooth 1.5 with insufficient ferrule effect. Clinical crown lengthening in the esthetic zone. This is a topic that has guidelines, but a review of the scientific literature produces few hard and fast rules. MeSH One significant feature of gingival morphology is the gingival line, which is defined as a line joining the tangents of the gingival zeniths of the central incisor and canine. Careful pre-surgical evaluation and planning of the case is necessary to achieve the best result and preserve papilla.29. Patients with thick tissue biotype demonstrate significantly more coronal soft tissue regrowth than patients with thin biotype due to the biological differences in respective healing responses. To predict the final esthetic result and achieve optimum results in gingival contour rehabilitation (crown lengthening, implant, and orthodontic therapy), it is important to take the gingival contour into account during treatment planning. Dec 1999;4(1):98-101. A common consensus is that, when the biologic width is violated, the body will attempt to redefine it by a process of osseous resorption. The aesthetic smile: diagnosis and treatment. Improving gingival smile by means of guided bone regeneration principles. Clinical Crown Lengthening by Surgical Extrusion: A Case Report. 0000009226 00000 n There are differences between the two procedures that you will want to discuss with your doctor as you plan your treatment.

HHS Vulnerability Disclosure, Help A guide to minimally invasive crown lengthening and tooth preparation for rehabilitating pink and white aesthetics. The removal of remaining root cementum with inserting collagen fibers will prevent reattachment of the surgically separated fibers in an undesired coronal position.32. Clipboard, Search History, and several other advanced features are temporarily unavailable. Thereafter, it is the passive eruption, which is the migration of the epithelial attachment apically to expose the anatomic crown of the tooth, that determines the final appearance of the tooth/gingival complex. A ratio of 1:1 may even be acceptable if the opposing occlusion is a tissue-supported prosthesis. It was reported that subjects with pronounced scalloped gingiva often exhibited more advanced soft tissue recession in the anterior maxilla than subjects with a flat gingiva.23 Biotype assessment based on visibility of periodontal probe through the gingival margin has been shown to be a simple, reliable, and reproducible method for gingival thickness assessment in routine practice.24, Although there is no generally accepted value, if subgingival margins are indicated, they should not extend beyond 0.5mm subgingivally.25,26 The biological width can be violated when a restoration is placed deep within the subgingival tissues. Misdiagnosis followed by poor choice of procedure and lack of skills to perform it can lead to unfavorable results. Ideally, the tooth would have at least 8 mm of root length in bone; less length would increase risk. In addition, she is a graduate of the American Board of Periodontology. Br Dent J. With the continued high demand for esthetic dentistry, gingival health is among the first fundamental esthetic objectives during treatment planning. Betsy Bakeman, DDS, is a mentor at the Kois Center in Seattle, Washington, and a dentist in private practice in Grand Rapids, Michigan. Orthodontic extrusion, also known as forced orthodontic extrusion or forced orthodontic eruption, is defined as tooth movement caused by coronally directed orthodontic forces. Topics covered include teeth extractions, wisdom teeth, dental implants, bone grafting, orthognathic surgery, facial bones realignment, facial trauma repair, jaw alignment, anesthesia , jaw cyst or tumor diagnosis, reconstructive jaw surgery, temporomandibular joint syndrome (TMJ) and TMJ surgery. All manner of functional demands specific to the situation must be considered when making the decision to restore or remove a structurally compromised tooth, such as the location of the tooth in the mouth and whether the patient exhibits signs of acceptable or pathologic function. doi: 10.1016/j.joen.2011.09.024. Ochenbein and Ross21 and Becker et al.22 proposed that the anatomy of the gingiva is related to the contour of the osseous crest, and that two basic types of gingival architecture may exist, namely the pronounced scalloped and the flat biotype. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). J Periodontol. Crown lengthening may be as simple as a limited removal of soft tissue or as complex as orthodontic extrusion followed by flap with osseous surgery on a tooth requiring endodontic therapy. In my opinion, the only important issue they have missed to elaborate is the "orthodontic forced eruption (OFE) or orthodontic extrusion . Federal government websites often end in .gov or .mil.

If the facial free gingival margin is coronal to the desired position, then crown lengthening may very well satisfy both the esthetic and the biomechanical requirements. Most importantly, the patient should be given the options that are available and the risks/benefits associated with these options. Is the tooth being super-erupted? V. Kim Kutsch, DMD, is a mentor at the Kois Center in Seattle, Washington, and a dentist in private practice in Albany, Oregon. 4).31, Following osseous recontouring, in order to remove any possible remnant of connective tissue attachment coronal to the alveolar crest, the exposed root surfaces should carefully be planed with sharp curettes or rotating flame-shaped finishing burs. The goal of the crown-lengthening therapy is to enable the dentist performing the restoration to develop an adequate area for retention of the restoration. Therefore, it is of utmost importance when planning surgical crown lengthening to evaluate and measure the attached gingiva.29, The width of attached gingiva can be identified for each individual patient by probing under anesthesia to the bone level (referred to as bone sounding) and subtracting the sulcus from the resulting measurement. The flat (thick) gingival biotype subjects have incisors with squared crown form with pronounced cervical convexity. Forced Orthodontic Extrusion: A Practical Therapy Method for Apparently Hopeless Teeth? The patient is going to. -, Torabinejad M., Anderson P., Bader J., Brown L.J., Chen L.H., Goodacre C.J., Kattadiyil M.T., Kutsenko D., Lozada J., Patel R., et al. It reshapes your gums to expose more of your teeth, so your teeth look longer. Furthermore, if crown lengthening could be performed functionally because the teeth are stable, not mobile, surrounded by healthy periodontal tissues, but the proposed final restorative margins are expected to be so deep that the final restoration would be anything but cosmetic, then the authors believe that extraction followed by the replacement with either a dental implant or fixed partial denture would be a better treatment choice. School of Dental Medicine, Tufts University, Boston, MA, USA. Would you like email updates of new search results? Although an ideal crown-to-root ratio may be 1:2, a ratio of 1:1.5 may be acceptable if there is healthy periodontium and the occlusion is controlled. An official website of the United States government. Diseased gingival tissues will possess a negative impact on a smile. Dental update. Total treatment could thus involve endodontic, orthodontic, periodontic, and restorative procedures. Most dentists do not accomplish orthodontic extrusion or bony crown lengthening. The aim of the present narrative review is to compare advantages, disadvantages, time of therapy required, contraindications and complications of both techniques. A high-caries-risk patient places additional future risk on a restoration from a decay standpoint in addition to the biomechanical issues. 2007;98:285311. 2010 Jun;141(6):647-55. Grossmann Y, Sadan The prosthodontic concept of crown-to-root ratio: a review of the literature. These data could be used as reference points during esthetic anterior oral rehabilitation.14. An understanding of various techniques and proper planning are critical. And that decision should include a well-informed patient and be based on our best evidenced-based predictability of the treatment outcomes. A prosthesis will place additional stress on the existing root. Traumatol. Then decisions regarding viability of individual teeth make more sense in the big picture. 0000010581 00000 n doi: 10.1046/j.1365-2591.2002.00557.x. The site is secure. There comes the point where you are repairing previous repairs rather than repairing actual tooth structure. 0000011632 00000 n Rajendran et. Sep 2000;31(8):553-556. The present technique proposes a modified simplified surgical extrusion that does not entail the use of advanced instruments and preserves the root dentin. Crown lengthening is a procedure to address an excessive gingival display, otherwise known as a gummy smile. 2019;35:368375. 1 A). Someone may also undergo this surgery to make the teeth look longer if they have a gummy smile. 0000001667 00000 n Some clinicians advise that for every millimeter of extrusion, there needs to be 4 weeks of retention [ 44 ]. Crown-lengthening procedures are very predictable and should be performed using a systematic approach. The decision comes down to which approach is going to yield the best long-term result, be the least aggressive, and which is better for the overall health of the patient. Listgarten M. Ultrastructure of the dento-gingival junction after. From the bio-mechanical point of view when orthodontic extrusion is performed, bone support reduces, but the coronal lever arm does not change.12. Unauthorized use of these marks is strictly prohibited. 2022;17(4):205-208. doi: 10.22037/iej.v17i4.38469. Decisions regarding the viability of individual teeth make more sense when considering the big picture. 0000003437 00000 n Surg. This procedure involves surgical removal of periodontal tissue to gain the required amount of tooth structure. Forced orthodontic extrusion to restore extensively damaged anterior and premolar teeth as abutments for single-crown restorations: Up to 5-year results from a pilot clinical study. Therefore, the long-term prognosis of the tooth is compromised, and an extraction with an implant replacement may be the better option for the patient. If the tooth has been restored extensively, has had root canal therapy, or has extensive decay, we know that the tooth is probably structurally compromised. 12-11 ). Weekly Wisdom: What is the ESA and Common Law? Bragger U, Lauchenauer D, Lang NP. This definition was based on a study by Gargiulo that measured the component parts of the dentogingival junction of normal human autopsy specimens. Ramfjord SFC, E.R. This procedure is best accomplished with an apically repositioned flap followed by the needed amount of ostectomy (removal of tooth-supporting bone) to establish the required biologic width, the distance between the proposed restorative margin, and the alveolar crest. Accessibility Preoperative radiograph (. 3).31 Proper surgical technique of apically repositioning flap may even increase the band of attached gingiva, despite the resective component of the procedure.29 In areas of insufficient zone of attached gingiva and alveolar crest located at the cemento-enamel junction, partial thickness flap and osseous resection should be perform in order to establish biological width (Fig. 17 ( 4 ):205-208. doi: 10.22037/iej.v17i4.38469 few hard and fast rules placed.
