Immediate versus conventional loading of variable-thread tapered implants supporting three- to four-unit fixed partial dentures in the posterior maxilla: 3-year results of a split-mouth randomised controlled trial.

Purpose: To compare the 3-year outcomes of immediately loaded and one-stage conventionally loaded variable-thread tapered implants in the posterior maxilla.

Materials And Methods: This study was designed as a split-mouth randomised controlled trial. Twenty-six patients attending the postgraduate Periodontics Department at the Lebanese University, and missing teeth bilaterally in the posterior maxilla were randomised.

Effect of patient- and surgery-related factors on supracrestal tissue reestablishment after crown lengthening procedure.

Objectives: The standard application of a mean value of 2.04 mm for the biologic width has been demonstrated to result in inconsistent amounts of tooth extension following a crown lengthening procedure. Biologic width has been replaced by the supracrestal gingival tissue dimension, which includes the biologic width and sulcular depth.

Comparison of fit accuracy of pressed lithium disilicate inlays fabricated from wax or resin patterns with conventional and CAD-CAM technologies.

Statement Of Problem: The use of resin patterns to produce partial coverage restorations is poorly documented.

Purpose: The purpose of this in vitro study was to compare the marginal and internal fit accuracy of lithium disilicate glass-ceramic inlays obtained from wax or resin patterns and fabricated with digital and conventional techniques.

Material And Methods: A dentoform mandibular first molar was prepared for a mesio-occlusal ceramic inlay.

Insertion Torque of Variable-Thread Tapered Implants in the Posterior Maxilla: A Clinical Study.

Purpose: Primary stability is a key factor for successful implant osseointegration, especially in poor bone quality and early/immediate loading. In the immediate loading protocol, insertion torque values (ITVs) have been suggested to be the most valid prognostic factor for osseointegration of maxillary implants. The objectives of this study were to: (1) evaluate ITVs achieved by a variable-thread tapered implant in the posterior maxilla; and (2) assess the impact of bone quality, implant dimensions, bicortical anchorage, and implant location on ITVs.

Marginal and internal fit of pressed lithium disilicate inlays fabricated with milling, 3D printing, and conventional technologies.

Statement Of Problem: The subtractive and additive computer-aided design and computer-aided manufacturing (CAD-CAM) of lithium disilicate partial coverage restorations is poorly documented.

Purpose: The purpose of this in vitro study was to compare the marginal and internal fit accuracy of lithium disilicate glass-ceramic inlays fabricated with conventional, milled, and 3-dimensional (3D) printed wax patterns.

Material And Methods: A dentoform mandibular first molar was prepared for a mesio-occlusal ceramic inlay.

Healing Time for Final Restorative Therapy After Surgical Crown Lengthening Procedures: A Review of Related Evidence.

Focused Clinical Question In healthy patients who receive surgical crown lengthening, how much healing time should be allowed for the positional changes of the gingival margin before final restoration? Clinical Scenario A 59-year-old woman presented to the University of Alabama at Birmingham School of Dentistry in August 2011 for replacement of her existing porcelain-fused-to-metal crowns on the maxillary anterior teeth for esthetic reasons. Clinical examination revealed a diagnosis of developmental mucogingival deformity manifested by gingival excess in the maxillary anterior sextant. An esthetic evaluation was performed and identified excessive gingival display attributable to short clinical crowns and excluded vertical maxillary excess and short or hypermobile upper lip as etiologic factors.
