METHODS: 63 ENT specialists responded to mailed questionnaire that include various sinus pathology scenarios. Their responses were statistically evaluated and analyzed. RESULTS: 58% recommend routine CT Scan prior to sinus-lift surgery. Patient symptoms that indicate referral to ENT prior to sinus grafting include nose problems and sinus issues. CT- scan findings that suggested a referral […]

METHODS: Thirty-one extraction sites were divided into the test group (Calcium Sulfate) and the control group (FDBA). At three months, sites were re-entered, ridge dimensions were measured and bone samples analyzed for new bone formation. RESULTS: Minimal change in the vertical ridge height for both groups. Both groups had significant decrease in bucco-lingual ridge width […]
METHODS: CT scans taken from 100 subjects were evaluated. Measurement points were taken from the gingival margin to the middle palatine suture at the canine, premolar, and molar sites. RESULTS: The mean thickness of the posterior palatal mucosa was 3.83 mm ± 0.58 mm. Thinner palate for females (3.66 ± 0.52 mm) compared to males […]
METHODS: Two different thread designs were compared. One group had a V-shaped thread design (Zimmer) and the other had a square-shaped thread design (Biohorizons). Immediate implants were placed with a surgical guide in a randomized split mouth design. The location of the implants after placement was measured to the closest millimeter. RESULTS: All implants placed […]
METHODS: A meta-analysis on prospective clinical trials yielded thirteen studies with 1,955 dental implants, of which 914 were short implants < 10 mm in length. RESULTS: Short implants had an estimated survival rate of 88.1% at 168 months, compared to a similar survival rate of 86.7% for standard implants (P=0.254). The peak failure rate for […]
METHODS: Sixty-four patients requiring crown lengthening on 64 teeth were included. Bone was reduced based on the minimal amount of tooth structure required for restoration. Patients were re-evaluated at 3 and 6 months. RESULTS: There was significant soft tissue rebound (0.77 ± 0.58 mm) at 6 months post crown lengthening surgery. The tissue rebound was […]
METHODS: Retrospective data was obtained from 23 patients who had undergone sinus augmentation procedures with a total of 40 treated sinuses. Sinuses were grafted with mineralized cancellous bone allograft, anorganic bovine bone matrix, or biphasic calcium phosphate. There were 15 perforated sinuses which were repaired with an absorbable collagen membrane. Histologic cores were taken from […]
METHODS: A meta-analysis was performed on eleven studies that compared marginal bone loss between implants restored with the following protocols: Immediate restoration/loading; early loading; conventional loading RESULTS: After adjusting for implant placement levels, no significant difference was found when comparing marginal bone loss for four scenarios: immediate restoration/loading + delayed placement versus conventional loading + […]
METHODS: Implant supported restorations were placed in 137 atrophic ridges that were augmented with cancellous block-bone allografts. Recipient site complications associated with block grafting were recorded. RESULTS: Total block-graft failure occurred in 7% of cases and partial block graft failure occurred in 8% of cases. The implant failure rate was 4.4%. Soft tissue complications included […]
METHODS: A retrospective study on 382 implants with peri-implantitis in 150 patients. Peri-implantitis was defined as pockets ≥ 5 mm, bleeding on probing or suppuration, and the presence of radiographic bone loss ≥ 3 mm or at least three threads of the implant. RESULTS: The mean time between implant installation and peri-implantitis was 6.4 years. […]
