Bone quality and implant design-related outcomes through stage II surgical uncovering of Spectra-System root form implants.

Failure rates at second-stage surgery were reported for the ongoing Dental Implant Clinical Research Group studies of the Spectra-System (Core-Vent Corporation, Las Vegas, NV) implants. As of May 1995, 69 implants failed out of 2,633 placed and uncovered. The overall failure rate was 2.6%, with 3.6% in bone quality 1 (BQ-1), 2.4% in BQ-2, 2.5% in BQ-3, and 3.1% in BQ-4. HA-coated cylinders had the lowest number of failures and titanium alloy baskets the highest. The basket design failed more often in the posterior jaw areas; 9 of 32 clinical centers (28%) accounted for 72% of these failures.

Histological evaluation of periodontal probe penetration in untreated facial molar furcations.

The purpose of this investigation was to histologically determine the position of the periodontal probe tip when probing the deepest interradicular pocket depth in grade II and III facial molar furcation sites. Facial furcation pockets (5.8 mm +/- 1.3) were probed with a pressure-sensitive probe set at 50 g pressure. The probe tip was attached to the tooth with an acid etched composite resin. Surgical block biopsies were removed, fixed, decalcified and processed for histological sectioning. Buccolingual serial sections (6 mu) were cut from 9 biopsies and apicocoronal serial sections were cut from 3 biopsies. The sections were histometrically analyzed. The probe tip penetrated the inflamed furcation connective tissue an average depth of 2.1 mm (+/- 0.6). The probe tip was located 0.4 mm (+/- 1.4) apical to the crest of the interradicular bone. The % of inflammatory cell infiltrate in the connective tissue (ICT) around the probe tip was 56% (+/- 15%). There was no correlation between the % of ICT and the depth of probe penetration. This investigation demonstrated that probing of untreated facial molar furcation sites does not measure the attachment level of the interradicular root surfaces, but rather records the depth of probe penetration into the inflamed furcation connective tissue.

Hematologic and surgical management of the dental patient with plasminogen activator deficiency.

Anticoagulation therapy is used to treat patients with a variety of hemostatic disorders in an attempt to prevent thrombus formation. A thorough understanding of the patient's medical history is essential before dental treatment that may require alteration of this anticoagulation therapy. Alteration of anticoagulation therapy should be undertaken only after consultation with the patient's physician because some patients are at greater risk than others for thrombus formation or hemorrhage. This case of a 29-year-old man with plasminogen activator deficiency illustrates how consultation can result in a coordinated treatment plan for medical and dental management formulated to help ensure safe surgical treatment for these medically compromised patients.

Inter-examiner reproducibility of probing pocket depths in molar furcation sites.

This investigation was designed to determine the reproducibility of probing pocket depths in maxillary facial and mandibular facial and lingual grade II and III molar furcation sites. 80 untreated molar teeth with 102 furcation invasions due to periodontitis were probed with a pressure-sensitive periodontal probe by 3 examiners. 8 sites per furcation were measured by each examiner at a single examination. The sequence of examiner probing was rotated in order to evaluate the effect of sequential probing. Tracings were made from radiographs of the inter-root separations in order to classify the interradicular space and to determine the effect of root separation on reproducibility. Data was analyzed by regression analysis. Pearson correlations, intraclass correlations, and the Student-Newman-Keuls test. Analysis indicated a high reproducibility of the maxillary facial and mandibular facial and lingual furcation sites in this untreated adult sample. No effect was due to probing sequence. The mid-root prominences, the line angles, and the internal surface sites of the furcation roots were recordable and reproducible, while the horizontal measurements were not consistently recordable. The reproducibility of the facial and lingual furcation sites that were probed decreased with an increase in probing pocket depth and an increased degree of root separation.
