Forced eruption and implant site development: an osteophysiologic response.

Before selected hopeless teeth were extracted, the authors orthodontically erupted these teeth to augment the three-dimensional topography of future implant recipient sites. This controlled "biodynamic orthodontic modeling" manipulates teeth, with as little as one fourth to one third of their apical attachment intact, by constructively increasing their local osseous dimensions in the vertical plane. Such vertical remodeling, especially of the strategic labial plate and crest, allows a more ideal placement of the implant (within 1 to 3 mm apically, depending on implant type) in relation to the cementoenamel junction of the adjacent dentition. The more coronal the placement of the implant head, without compromising esthetics, the more readily maintainable the peri-implant soft tissue environment is likely to be, because of the potential for decreased sulcular depth.

Esthetic soft tissue profile preferences among the Japanese population.

The purpose of this study was to determine the facial profile preferences in a sample of 2651 randomly selected panelists (mean age, 29.3 +/- 10.1 years) from Japanese cultural and educational backgrounds. Five facial profile types were computer-generated by an orthodontist to represent distinct facial types. Subjects were asked to rank the profiles in descending order of attractiveness. The ranking was as follows: orthognathic profile, bimaxillary retrusive profile, bimaxillary protrusive profile, mandibular retrognathic profile, and mandibular prognathic profile. The differences in rank scores between all the profile types were statistically significant (p < 0.05).

Case report: forced eruption and implant site development.

It is now possible to use the orthodontic extrusion of periodontally compromised teeth to facilitate the development of a future implant site in an area where the amount of bone in the inciso-apical dimension would otherwise have been inadequate. The purpose of this case report was to analyze the hard and soft tissue changes when forced eruption is used for implant site development.

Forced eruption and implant site development: soft tissue response.

The increased use of implants in orthodontics has stimulated interest in augmenting bone in patients who have deficient alveolar ridges that preclude ideal implant placement. A nonsurgical technique for increasing the amount of available bone for implant site development and fixture placement is orthodontic extrusion, or forced eruption. The concept of a tooth moving coronally by orthodontic means and the clinical alterations in the soft tissue architecture of the periodontium demonstrated during orthodontic extrusive movement of periodontally compromised teeth have demonstrated a direct relationship of pocket depth reduction, accompanied with an immature appearing tissue, "the red patch." This article will describe the periodontium during eruptive tooth movement.

Esthetic recontouring. A team approach.

The presence of irregular incisal edges, a worn or abraded dentition, and imbalances in tooth morphology compromise a harmonious esthetic smile. A team approach is indicated after extensive orthodontic or prosthetic treatment to reach a final cosmetic result. Intentional changes in tooth form by recontouring provide an improved outcome. This article presents the components of a harmonious smile, evaluation, guidelines and a stepwise approach for the esthetic recontouring of anterior teeth. Two cases illustrate the effects that are achieved with this methodology.
