In order to reestablish a physiological supracrestal tissue attachment of damaged teeth and to arrange an efficient ferrule effect, three options can be considered: crown lengthening, orthodontic extrusion and surgical extrusion. Functional crown lengthening is a periodontal surgical procedure that is usually used to increase the size of the available clinical crown, expose the entire anatomic crown, or establish the proper amount of biologic width. Dental Press J Orthod. 0000015429 00000 n McGuire MK, Nunn ME. 0000013520 00000 n It does not asses mobility, buccal and lingual alveolar bone support, root configuration and angulation and opposing occlusion.9 Nevertheless, the ideal crown to root ratio has been suggested to range from 1:2 or 1:1.5 with a suggested minimum ratio of 1:1.10 Though, it is still unclear how this ratio affects prognosis.11 Disadvantages of surgical crown lengthening treatment are an increase in crown/root ratio caused by the reduced effective root length and the increased effective crown length and the reduced volume of remining root dentin. A Comparative Evaluation for Biologic Width following Surgical Crown Lengthening Using Gingivectomy and Ostectomy Procedure. Conclusion: Regardless of the surgical approach soft or hard tissue reduction preservation of interproximal papillae is an integral part of success. To provide magic numbers for the clinician, mathematic theorems as the golden proportion and golden percentage have been proposed. Charruel S, Perez C, Foti B, Camps J, Monnet-Corti V.

Orthognatic procedures may also be suggested as a treatment option for repositioning of the maxilla. I believe there are a couple of major considerations. The flat (thick) gingival biotype subjects have incisors with squared crown form with pronounced cervical convexity. Nordland and Tarnows classification of a normal interdental papilla is one that fills the embrasure space to the apical extent of the interdental contact area.13 Deviation from the normal interdental papilla will result in an undesirable gingival black triangle and gingival asymmetry that can lead to a visual stress and imbalance.14 As mentioned, the essential of a smile involves the relationship among the teeth, the lip framework and gingival scaffold. The authors declare no conflict of interest. Signs of parafunction or premature loading of teeth during function decrease the long-term prognosis for a structurally compromised tooth. 2).30, In cases of insufficient width of attached gingiva and when the alveolar crest is at 1.5-2.0 mm from the cemento-enamel junction, the gingival tissue will be repositioned apically (Fig. Bone Grafting / Tissue Regeneration Materials. Active eruption ceases when the teeth come into contact with the opposing dentition. 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. An example would be an endodontically treated maxillary incisor that has fractured close to the soft-tissue level. 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.

Multidisciplinary and esthetic approach to clinical crown lengthening: report of a case. Single-tooth treatment decisions should always be made in the context of the overall treatment goals for the patient. 0000001876 00000 n The final outcome also depends of the proportion of the size of the teeth between each other and how much of tooth is showing. data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAKAAAAB4CAYAAAB1ovlvAAAAAXNSR0IArs4c6QAAHCNJREFUeF7tnQd0VFXXht+ZSQ8lIYFEqmBoiiAiTYpSBGkWQJrto9mooYOACooURanSBQQ . Ideally, the tooth would have at least 8 mm of root length in bone; less length would increase risk. Patients with greater susceptibility to decay have a poorer prognosis for the long-term retention of a structurally compromised tooth. Tal Rapoport graduated dental school from the Hebrew University and has practiced dentistry since 2006. An official website of the United States government. Either way, there is no sound justification, clinical or scientific, to ignore the biological width as an anatomical and functional entity in the practice of restorative dentistry.27,28, Treatment Therefore, removal of the tooth and placement of an implant remain as the most predictable and viable solution. In cases of a wide zone of attached gingiva, treatment can include gingivectomy and gingivoplasty (Fig. Conventionally, bridges are made . The https:// ensures that you are connecting to the Surgical extrusion of 1.2 tooth with insufficient ferrule effect. 0000001208 00000 n 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. 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. Bruhnke M, Bitter K, Beuer F, Bse MWH, Neumeyer S, Naumann M. Quintessence Int. 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. The .gov means its official. Crown lengthening is usually performed for . 6. Orthodontic therapy to extrude tooth 1.5 (, Surgical extrusion of tooth 1.2 with insufficient ferrule effect (, Surgical extrusion of 1.2 tooth with insufficient ferrule effect. 8600 Rockville Pike Histogenesis of repair following osseous surgery. 5. 2020 Nov/Dec;33(6):684-688. doi: 10.11607/ijp.6561. Is there mobility? An appropriate ferrule is a significant factor in improving resistance to fracture. What Is the Best Temporary Crown Material? The. An alternative to surgical crown lengthening is orthodontic forced eruption, it is non-invasive, does not remove or damage the bone and can be cost effective. 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. In instances where the pretreatment free gingival margin is equal with or apical to the desired position, then crown lengthening may satisfy the biomechanical requirements of the situation, but at the expense of the esthetic requirements. Int J Prosthodont. With the high long-term success rates for implant-supported restorations, it is important to measure all of the factors that go into a decision to restore or remove a tooth beyond the consideration to crown lengthen the tooth. Crown lengthening is a procedure to address an excessive gingival display, otherwise known as a gummy smile. Cases that combine altered passive eruption with maxillary hyperplasia, should first be treated for any altered relationship between gingiva and cemento-enamel junction. %PDF-1.4 % 72 0 obj << /Linearized 1 /O 74 /H [ 1281 386 ] /L 368399 /E 64759 /N 6 /T 366841 >> endobj xref 72 43 0000000016 00000 n Authors Martina Cordaro 1 2 3 , Edoardo Staderini 1 2 , Ferruccio Torsello 1 2 , Nicola Maria Grande 1 3 , Matteo Turchi 1 2 , Massimo Cordaro 1 2 The ultimate emergence of the final restoration on a narrower root form and the esthetic implications of this must also be considered. With the improvements in our clinical surgical techniques and the proven effectiveness and predictability of implants, the line between when to crown lengthen and when to extract has become more and more indistinct. 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. J. Korean Assoc. Width measurements of the epithelial attachment were found to be the most variable and the connective tissue attachment dimensions were the most constant.17 There is some controversy as to what the term biological width encompasses. Selection of best-suited treatment modality depends on patients' requirements and indications of the procedure. Gargiulo Dimensions and relations of the dentogingival junction in humans. In this case, an extraction with implant placement may be the better option for the patient. Additional variables should include the history of the tooth, such as whether this was a dental caries problem or caused by restoration/tooth failure or trauma. Federal government websites often end in .gov or .mil. School of Dental Medicine, Tufts University, Boston, MA, USA. Vacek JS, Gher ME, Assad DA, Richardson AC, Giambarresi LI. Deas DE, Mackey SA, Sagun RS, , Hancock RH, Gruwell SF, Campbell CM. Orthodontic extrusion, also known as forced eruption, has been developed and employed clinically to serve the purposes of increasing the clinical crown length, correcting the periodontal defect, and developing the implant site. Quintessence international. 0000008538 00000 n For successful treatment, the dentist must consider what the crown-to-root ratio will be after crown lengthening is performed. Orthodontic Extrusion vs. Surgical Extrusion to Rehabilitate Severely Damaged Teeth: A Literature Review Int J Environ Res Public Health. Lastly, if the recurrent decay was so deep into the tooth and under the existing gum line that after crown lengthening and removal of all the recurrent decay the tooth would become class II or III mobile, or the tooth was so undermined by the decay that there seemed to be a high probability of tooth fracture after restoration, then the authors believe that extraction rather crown lengthening would be the better treatment of choice. This complex includes the sulcus, the junctional epithelial attachment, and dentogingival fibers.
