Lip repositioning with or without myotomy: A randomized clinical trial.

Background: Lip repositioning is a conservative surgical method for the correction of excess gingival display (EGD) by limiting the upward retraction of the lips. Lip repositioning presents a simple method for the treatment of gummy smile. The aim of this randomized clinical trial (RCT) was to assess lip repositioning, compared to lip repositioning with muscle severance for efficacy in treatment of EGD and resultant stability.

In vitro evaluation of marginal discrepancy of monolithic zirconia restorations fabricated with different CAD-CAM systems.

Statement Of Problem: Dental laboratories use different computer-aided design and computer-aided manufacturing (CAD-CAM) systems to fabricate fixed prostheses; however, limited evidence is available concerning which system provides the best marginal discrepancy.

Purpose: The purpose of this in vitro study was to evaluate the marginal fit of 5 different monolithic zirconia restorations milled with different CAD-CAM systems.

Material And Methods: Thirty monolithic zirconia crowns were fabricated on a custom-designed stainless steel die and were divided into 5 groups according to the type of monolithic zirconia crown and the CAD-CAM system used: group TZ, milled with an MCXL milling machine; group CZ, translucent zirconia milled with a motion milling machine; group ZZ, zirconia milled with a dental milling unit; group PZ, translucent zirconia milled with a zirconia milling unit; and group BZ, solid zirconia milled using an S1 VHF milling machine.

Dental implants combined with sinus augmentation: What is the merit of bone grafting? A systematic review.

Purpose: The aim of the present study was to systematically assess the current evidence on the effect of nongrafted compared to graft-assisted maxillary sinus floor elevation on implant survival/failure, endosinus bone gain, crestal bone loss, and bone density around dental implants.

Materials And Methods: MEDLINE-PubMed, Cochrane-CENTRAL, and EMBASE databases were searched up to November 2015 for randomized controlled trials (RCTs) and controlled clinical trials-(CCTs), evaluating dental implants placed in combination with maxillary sinus elevation without and with bone grafting. Implant survival/failure served as the primary outcome, whereas endosinus bone gain, crestal bone loss, and bone density around dental implants were secondary outcomes.

Meta-analysis of the Incidence of Lingual Nerve Deficits After Mandibular Bilateral Sagittal Split Osteotomy.

Introduction: Bilateral sagittal split osteotomy is a relatively common maxillofacial surgical procedure. The most commonly reported complication is neurosensory disturbances (NSD). The inferior alveolar nerve is by far the most commonly affected but sporadic reports of NSD of the lingual nerve also exist.

Bonding strategies to pulp chamber dentin treated with different endodontic irrigants: microshear bond strength testing and SEM analysis.

Purpose: To evaluate the effect of 6 irrigant regimens on the microshear bond strength of different adhesives to pulp chamber dentin and to determine their interfacial morphology by SEM.

Materials And Methods: Forty-three human molars were split into halves and ground to provide flat pulp chamber dentin. Eighty-five halves were used.
