Periodontal and dental considerations in clinical crown extension: a rational basis for treatment.

When the clinical crowns of teeth are dimensionally inadequate, esthetically and biologically acceptable restoration of these dental units is difficult. Often an acceptable restoration cannot be accomplished without first surgically increasing the length of the existing clinical crowns; therefore, successful management requires an understanding of both the dental and periodontal parameters of treatment. This report provides further insight into this interdependence by examining the effects of tooth form on the periodontal morphology and surgical treatment, while relating them to requirements for esthetically and biologically acceptable full-coverage dental restorations. This report also explains the role that restoration margin location and emergence profile play in the maintenance of periodontal and dental symbiosis. The effects of violation of the supracrestal gingivae by improper full-coverage restorations is also illustrated.

A scanning electron microscope study comparing the effectiveness of different types of sharpening stones and curets.

The effects of various types of sharpening stones on standard carbon steel Gracey type curets, and the influence of the sharpened curets on periodontally involved root surfaces, during in vitro scaling and root planing, was evaluated by means of scanning electron microscopy (SEM). Six different sharpening stones of varying texture, two of aluminum oxide, two India, and two Arkansas stones were assigned to sharpen six groups of 10 curets each. The curets were first examined under SEM and photographed and all exhibited edge irregularities. They were then sharpened with the different stones and again examined and photographed using SEM. The sharpness of each instrument was graded, related to the type of stone used, and the data compared statistically. A positive correlation was found between the texture of stone used and the surface sharpness it produced on the cutting edge of the instrument. The curets were then used to root plane the root surfaces on periodontally involved, extracted teeth. Replicas of the root surfaces were examined with SEM before and after removal of the smear layer with 10% EDTA. The planed and cleaned root surfaces revealed the effects of the sharpened instruments, with the relative surface roughness of the instrument being imparted to the tooth surface. The curets sharpened with finger grit stones produced smoother surfaces than those sharpened with the rough or coarse grit stone. It may be concluded that the sharpness of curets is related to the type of sharpening stone used and in turn to the smoothness of the planned root.

Ridge augmentation in preparation for conventional and implant-supported restorations.

Alveolar ridge defects from bone loss hinder esthetics during conventional restoration and preclude optimal positioning of implant fixtures for implant-supported restorations. Various methods of ridge augmentation to replace lost bone can remedy these complications. Recent advances in periodontology have enabled clinicians to address the problems of ridge augmentation in various ways. This article describes these methods, which include soft-tissue rearrangement, soft-tissue grafting, hard-tissue implantation, and alveolar bone regeneration.

The use of gingival autografts that contain submucosa in the repair of mucogingival defects in maxillary molars: case reports.

Many studies have shown that deep and wide gingival recessions can be predictably covered by free gingival autografts. Most of the autografts in these studies were performed on single-rooted teeth. This article presents a rationale for a new technique that repairs this type of defect in maxillary molar areas by means of thick masticatory mucosa autografts that intentionally include not only the lamina propria, but also portions of the submucosa. In addition, a new suturing approach that allows adequate adaptation of the donor tissue to the recipient site and permits relocation of the graft is proposed. This new approach has been shown to be a significant advantage in the anatomically problematic maxillary molar area.
