1/119. The profile prosthesis: an aesthetic fixed implant-supported restoration for the resorbed maxilla.

    This article discusses a method for the predictable fabrication of fixed detachable maxillary reconstructions that abut and precisely follow the gingival contours--regardless of implant angulation or position. The technique reorders the traditional implant protocol and delays abutment selection until the definitive tooth position has been established. In this manner, final abutment selection and framework design become a single, integrated process that results in improved aesthetics, reduced angulation difficulties, and elimination of the phonetic concerns traditionally associated with fixed maxillary prostheses.

2/119. guided tissue regeneration procedure applied to the treatment of endodontic-periodontal disease: analysis of a case.

    The clinical condition of a patient with chronic adult-type periodontal disease, as well as gingival recession reaching the tooth apex on a mandibular lateral incisor, is discussed. Because the use of conventional techniques would have resulted in tooth loss, the guided tissue regeneration procedure was applied, with successful results.

3/119. bone regeneration around an osseointegrated implant. A simultaneous approach in a fenestrated defect: a case report.

    The use of a barrier membrane, with or without osseous allograft, has been shown to establish regeneration of osseous tissue around dental implants. Following three episodes of persistent symptomatic failed apicoectomy and subsequent tooth extraction, an osseointegrated implant was placed in a wide fenestrated defect. Demineralized freeze-dried bone allograft was covered by an occlusive expanded polytetrafluorethylene membrane. The reentry procedure revealed complete bone fill that followed the texture of the augmentation material beyond the previous buccal bony envelope.

4/119. Effective periodontal treatment in a patient with type IIA von Willebrand's disease: report of a case.

    von Willebrand's disease (vWD) is one of the most common hereditary hemorrhagic disorders. A mild to moderate deficiency of factor viii and von willebrand factor (vWf) often is associated with gingival bleeding. In this case report, the periodontal treatment of a patient with vWD is described. A 45-year-old woman with type IIA vWD was referred for periodontal therapy because of an episode of gingival hemorrhage and percussion pain of teeth #18 and #47. The periodontal findings included probing depths ranging from 2 to 6 mm, horizontal bone loss, and Class II furcation involvement of tooth #46. After consultation with a hematologist, apically positioned flap surgery and hemisection were performed on tooth #46 following completion of oral hygiene instruction, scaling and root planing, and endodontic therapy. The patient was given 500 units of factor viii including vWf multimer 30 minutes before surgery. After healing of the periodontal tissue, prosthodontic treatment was undertaken on the posterior mandibular sextants. At follow-up, the probing depths ranged from 2 to 3 mm, and gingival bleeding on probing was minimal. The patient's children all had vWD. They had mild to moderate periodontitis with probing depths ranging from 2 to 5 mm and gingival bleeding on probing. With the combined efforts of the periodontist and hematologist, effective periodontal treatment can be provided to patients with von Willebrand's disease.

5/119. case reports offer a challenge to treatment strategies for immediate implants.

    The placement of osseointegrated implants in extraction sockets is a commonly used and reliable procedure. Many operative protocols have been suggested for use with both submerged and nonsubmerged implants, and some prerequisites have been defined for their successful placement. Dealing exclusively with implants placed in intact extraction sockets, this paper reviews these commonly suggested prerequisites, discusses their clinical relevance, and presents case reports in which clinical success was obtained despite the violation of more than 1 of these factors. Techniques to obtain primary implant stability, procedures to regenerate residual bone defects, the need to submerge implants in the healing phase, and treatment strategy in infected sites are reviewed. Because the simultaneous violation of some prerequisite factors allows postextractive implants to be performed with a single surgical approach, a new classification is proposed based on the number of surgical stages required to replace a failing tooth with an implant-supported restoration.

6/119. Esthetic restoration of a single-tooth dental implant using a subepithelial connective tissue graft: a case report with 3-year follow-up.

    This case report describes the use of a subepithelial connective tissue graft to restore the gingival papillae and augment ridge soft tissues adjacent to a dental implant. The patient was referred for periodontic and prosthodontic evaluation after the placement of an implant--with the implant head 6.5 mm below the adjacent cementoenamel junction--in an area of inadequate bone volume with deficient interproximal papillae and ridge soft tissues. The resulting esthetic defect was restored by means of a combined technique that used a subepithelial connective tissue graft and an emergence profile-contoured crown. A 3-year clinical follow-up with complete regeneration of the gingival papillae is described.

7/119. Leukocyte adhesion deficiency in a child with severe oral involvement.

    Leukocyte adhesion deficiency is a rare inherited defect of phagocytic function resulting from a lack of leukocyte cell surface expression of beta2 integrin molecules (CD11 and CD18) that are essential for leukocyte adhesion to endothelial cells and chemotaxis. A small number of patients with leukocyte adhesion deficiency-1 have a milder defect, with residual expression of CD18. These patients tend to survive beyond infancy; they manifest progressive severe periodontitis, alveolar bone loss, periodontal pocket formation, and partial or total premature loss of the primary and permanent dentitions. We report on a 13-year-old boy with moderate leukocyte adhesion deficiency-1 and severe prepubertal periodontitis. This case illustrates the need for the dentist to work closely with the pediatrician in the prevention of premature tooth loss and control of oral infection in these patients.

8/119. Contemporary treatment of the resorbed avulsed tooth: a case report.

    This report describes the treatment sequence after traumatic loss of a maxillary central incisor in a 15-year-old patient. Following extraoral root canal treatment and initially successful replantation, the case presented 9 years later with complete root resorption. After augmentation with an autologous mandibular corticocancellous graft, a dental implant was placed in a second stage surgery. The case highlights the challenge facing clinicians in providing the appropriate standard of care for today's treatment options.

9/119. Radiographic bone fill following debridement of a periodontal abscess. A case report.

    A periodontal abscess often develops in association with deepened periodontal pockets. Traditional management is by establishing drainage and prescribing antibiotics. This is usually followed by surgical pocket reduction. This case report discusses the remarkable healing of a periodontal abscess by establishing drainage alone without resorting to surgical pocket reduction. A 42-year-old white male presented with swollen gingivae associated with the mesiolingual of tooth #23. Increased probing depth and suppuration were evident. Radiographic bone loss on mesial #23 was present. A diagnosis of periodontal abscess was established. The abscess was drained through the orifice of the pocket. The patient failed to return for follow-up as instructed. A year later, the patient came back. Clinical evaluation showed healthy gingival tissues with probing depth of 3 mm on the mesiolingual of tooth #23. Radiographic evaluation showed bone fill of the osseous defect on the mesial of #23. The results of this case suggest that sufficient time should be allowed for healing prior to surgical pocket reduction.

10/119. Aesthetic management of extractions for implant site development: delayed versus staged implant placement.

    Resorption of the dentoalveolar bone and collapse of the gingival ridge following tooth loss often results in aesthetic compromise and inadequate bone for "prosthetically driven" implant placement. Preventing alveolar bone resorption with a conservative procedure at the time of extraction can enhance aesthetics and reduce the duration and extent of treatment required for implant placement. This article describes the aesthetic management of extraction sites using a conservative bone grafting procedure at the time of extraction for implant site development. The case presented demonstrates staged and delayed implant placement techniques.
