ABSTRACT
Conventional implant therapy dictates a period of 1 to 2 years from the start of treatment to the completion of the restoration. In contrast, immediate implant placement has resulted in the initiation of prosthetic treatment in as little as 3 to 6 months with the additional benefit of reducing alveolar bone resorption, patient morbidity, and expense. This article reports on the criteria for immediate implant placement into an extraction socket, as well as a reliable technique and a retrospective analysis of 1,081 implants placed immediately into extraction sockets. Of the 1,081 implants placed, 35% were followed for 1 year, 46% were followed for 2 to 5 years, and 19% for 5 to 11 years postloading. The criteria for success were complete stability and no further bone loss than had appeared at the second stage surgery and on the day of restoration. The overall survival rate in this current study is 95%.

Oligodontia, the congenital absence of numerous teeth, presents many problems for both patient and therapist. Chief among these is the sequence and timing of orthodontic therapy, implant placement, and restorative dentistry. The absence of teeth can pose not only functional but psychosocial problems for young people. This report details a young woman who was diagnosed with oligodontia at age 9, treated using a multidisciplinary approach, and followed for 12 years.

The treatment of young people with implants requires advanced planning and coordination of many different specialities within dentistry. Timing and sequence of therapy will often decide the success or failure of treatment. Congenital absence of many teeth (oligodontia) associated with or without syndromes poses not only functional but also psychosocial problems for young people. A case is presented in which orthodontist, restorative dentist, and periodontist evaluated and performed the necessary therapy for a young person who at the age of 9 was diagnosed with oligodontia/l. Nine implants were placed: 13 years, 8 months in the mandible and 15 years, 6 months in the maxilla. All implants were restored as single teeth. The patient was followed until age 20.

This article describes two common varieties of osseous lesions within the furcation--hemifurcal and crescent-intrafurcal defects--and their appropriate management. Although hemifurcal lesions are difficult to assess both radiographically and clinically, once they are diagnosed, they can be readily resolvable using a self-regeneration procedure or an osseous graft. Crescent-intrafurcal defects are more common than hemifurcal lesions and can be discerned more easily on radiographs than clinically. The treatment of a crescent-intrafurcal defect focuses on minimizing the vertical component. Self-regeneration or osseous grafting is considered an appropriate treatment course.

Uprighting and extrusion are two movements that are used to aid in the treatment of difficult periodontal and restorative problems. Simple appliances can be used to alter tooth position, enhancing either the periodontal therapy, restorative dentistry, or both. Treatment time can be limited to 3 to 6 months.

Evaluation of periodontal status and proposed orthodontic therapy must be made prior to initiating tooth movement. Teeth with a compromised periodontium can be treated. Prior to initiation of orthodontic therapy, it may be necessary to perform periodontal surgery for pocket elimination or reduction, to perform mucogingival surgery, or to correct gross occlusal discrepancies.

Osseous defects not amenable to conventional resective or regenerative osseous surgery alone may respond to a combination of orthodontic and periodontal techniques. Two orthodontic procedures-correction of mesially tipped teeth and forced eruption-have been described that may enhance the periodontal prognosis. Each procedure is accomplished with use of sectional orthodontic appliances and each requires a short time for treatment. Beneficial results include improvement of the crown-to-root ratio, reception of the forces of occlusion in the long axis of the tooth, and reduction or elimination of infrabony defects.

Treatment for uprighted abutment teeth that may have infrabony pockets can be considered complete when the following criteria are met: 1. The uprighted tooth is in its proper vertical axis. 2. There is a significant decrease in soft-tissue pocket depth. 3. Crestal leveling is evident radiographically. 4. Adequate space has been created to accommodate a pontic (minimally 6.5mm). The advantages of employing this orthodontic-periodontal technique are as follows: 1. Leveling of the osseous crest fosters pocket elimination obviating the necessity for removal of a great deal of supporting bone. Concomitantly, a significant decrease in pocket depth usually eliminated the need for periodontal surgery. 2. The resulting occlusal forces are placed in favorable axial inclinations. 3. There is an improved crown-to-root ratio, since the uprighted and extruded tooth is reduced to the level of the occlusal plane. This reduction is sufficient to improve considerably the prognosis of a questionable abutment tooth. 4. A pontic space is created for an esthetic and properly contoured pontic. 5. Parallelism is attained, so that the marginal integrity is more easily accomplished. 6. The orthodontic procedures are relatively uncomplicated, efficient, and esthetic, provided there is little or no lower anterior crowding. 7. The restorative dentist has a proper abutment tooth with a good prognosis for prosthesis.

Selected cases have been presented using different techniques to alter crestal levels. Self Regeneration or Autogenous bone grafts have been most successful in cases of three-wall and two-wall infrabony lesions. When a hemiseptal lesion occurs on the mesial of a tooth an uprighting procedure can be accomplished. When there is an adjacent tooth a forced eruption technique using orthodontic forces can be used. A surgical elevation technique has been presented which also has shown positive changes in bony topography.
