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 … Continue reading →
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 … Continue reading →
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 … Continue reading →
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 ± … Continue reading →
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 … Continue reading →
When is it necessary to refer patients to an Ear, Nose and Throat Specialist prior to sinus grafting?
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 … Continue reading →
Methods: Beagle dogs were assigned to three groups with 16 sites each: Group 1: Single tooth extraction and one immediate implant Group 2: Two adjacent teeth extractions and one immediate implant Group 3: Three adjacent teeth extractions and one immediate implant Jaw segments were analyzed for bone thickness, marginal bone loss and bone to implant … Continue reading →
Methods: Split mouth design with 26 sites treated with Puros Dermis and 26 sites treated with Alloderm. A coronally advanced flap was used. Results: At 6 months both groups had similar improvements in recession coverage with an average of 2.83 mm for Puros Dermis and 3.13 mm for Alloderm. 81.4% root coverage for Puros and … Continue reading →
Methods: 195 CT scans from a private practice were examined. Measurements were made with computer software (Simplant) at 5mm intervals. Patients were categorized as to age, sex, and missing posterior teeth. Results: The following data emerged at the 95% confidence level (Excerpted from Table 1): Distance from the crest to the inferior alveolar nerve at … Continue reading →
Are Results for Enamel Matrix Derivative (Emdogain) comparable to Connective Tissue Grafting at 10 years?
Methods: 10 years after the original surgery for gingival recession, 10 of 17 patients were returned for follow-up evaluation. Among the parameters measured at 10 years: Percent root coverage, gingival recession depth, probing depths , width of keratinized tissue and clinical attachment levels. Results: No difference between Emdogain and Coronally Advanced Flap when compared to … Continue reading →
