Harvest graft substitute for soft tissue volume augmentation around existing implants: A randomized, controlled and blinded multicenter trial.

Background: Using a single-blind, randomized, controlled, multicenter, practice-based clinical trial, a volume-stable collagen matrix (VCMX) was compared with connective tissue graft (CTG) for soft tissue augmentation around existing dental implants.

Methods: Sixty patients (31 VCMX and 31 CTG) were included. The primary outcome was a soft tissue thickness change 3 mm below the gingival margin (GM).

A comparison of Er,Cr:YSGG laser to minimally invasive surgical technique in the treatment of intrabony defects: Twelve-month results of a multicenter, randomized, controlled study.

Background: The purpose of this publication is to report on the 12-month clinical and radiographic results comparing the surgical use of the Er,Cr:YSGG laser (ERL) and minimally invasive surgical technique (MIST) for the treatment of intrabony defects in subjects with generalized periodontitis stage III, grade B.

Methods: Fifty-three adult subjects (29 females and 24 males; 19-73 years) with 79 intrabony defects were randomized following scaling and root planing (SRP) to receive ERL monotherapy (n = 27) or MIST (n = 26). Fifty subjects completed the study.

A Prospective, Randomized, Controlled, Multicenter Evaluation of Extraction Socket Management Comparing a Wound Dressing and a Soft Tissue Substitute.

Postextraction bone grafting and implant placement help preserve alveolar bone volume. Collagen wound dressings and soft tissue graft substitutes may help protect extraction socket bone grafts and provide better gingival contours. This randomized, controlled, multicenter, and double-blinded study was conducted to compare a control (wound dressing) and a test (soft tissue graft) substitute in nearly intact extraction sockets.

Virucidal Properties of Molecular Iodine Oral Rinse Against SARS-CoV-2.

Background: Saliva is an active carrier of SARS-CoV-2, and antimicrobial mouthrinses can be rendered less effective by saliva. Aerosol-generating procedures are commonplace in dentistry, and preprocedural mouthrinses and/or irrigation with effective SARS-CoV-2 virucidals should be tested in the presence of saliva.

Methods: With the use of an in vitro virucidal suspension test, molecular iodine oral rinse was assayed against SARS-CoV-2 with and without saliva after 30- and 60-second exposures to the rinse.

Evaluation of a porcine collagen matrix used to augment keratinized tissue and increase soft tissue thickness around existing dental implants.

Implant-supported prostheses often present with mucogingival deficiencies that may cause esthetic or hygienic issues. These issues may present as limited or no keratinized tissue, irregular soft tissue contour or concavity, and gray "showthrough" of the implant abutment and root forms. An interpositional soft tissue graft substitute that generates keratinized tissue and increases soft tissue thickness would be beneficial, as it would reduce donor site morbidity and be available in unlimited, off-the-shelf supply.

Periodontal Regeneration - Intrabony Defects: Practical Applications From the AAP Regeneration Workshop.

Focused Clinical Question: What are important considerations for selecting a predictable regenerative surgical approach for intrabony defects? Summary: The predictable regeneration of intrabony defects remains an important goal in the management of periodontitis. Clinical and histologic evidence of periodontal regeneration has been shown for multiple regenerative therapies, including bone replacement grafts, guided tissue regeneration, and biologics, when used alone or in combination. Regenerative therapies improve periodontal health, as evidenced by gains in clinical attachment level, reductions in probing depth, and gains in radiographic bone fill.

Periodontal regeneration - intrabony defects: a consensus report from the AAP Regeneration Workshop.

Background: Treatment of intrabony defects is an important therapeutic goal of periodontal therapy. The goal of this consensus report was to critically appraise the evidence for the available approaches for promoting periodontal regeneration in intrabony defects. In addition to evaluating the effectiveness of new regenerative approaches for intrabony defects, recommendations for future research were defined for this area.

Dental implants' future: the need for a team approach.

Long-term success of dental implants is linked to well-trained implant surgeons and restorative dentists working together with the most advanced treatment modalities. General dentists are challenged to identify early in the diagnosis patients who are at greatest risk for developing complications and partner with specialists in formulating treatment plans.

Multicenter retrospective analysis of wide-neck dental implants for single molar replacement.

Purpose: To evaluate the predictability of Straumann wide-neck dental implants (6.5-mm prosthetic neck with a 4.8-mm endosseous sandblasted, large-grit, acid-etched-surface body) used for molar replacement.

Study of the Therapeutic Effects of Intercessory Prayer (STEP) in cardiac bypass patients: a multicenter randomized trial of uncertainty and certainty of receiving intercessory prayer.

Background: Intercessory prayer is widely believed to influence recovery from illness, but claims of benefits are not supported by well-controlled clinical trials. Prior studies have not addressed whether prayer itself or knowledge/certainty that prayer is being provided may influence outcome. We evaluated whether (1) receiving intercessory prayer or (2) being certain of receiving intercessory prayer was associated with uncomplicated recovery after coronary artery bypass graft (CABG) surgery.

Clinical, histologic, and histomorphometric evaluation of mineralized solvent-dehydrated bone allograf (Puros) in human maxillary sinus grafts.

Demineralized freeze-dried bone allografts (DFDBA) have been successfully used alone or in composite grafts for many decades. Little research has been done on the effect of retaining the mineral content of bone allografts. This study histologically and histomorphometrically evaluated a new mineralized bone allograft material placed in human atrophic maxillary sinuses.

Histologic evaluation of mineralized and demineralized freeze-dried bone allograft for ridge and sinus augmentations.

The objective of this study was to quantify new bone formation from biopsies of demineralized freeze-dried bone allograft (DFDBA) and freeze-dried bone allograft (FDBA) following ridge and sinus augmentations. Ninety-three patients who received maxillary sinus or ridge augmentation grafts agreed to core biopsies of their grafts when the implants were placed. Samples ranged from 6 to 36 months postgrafting.
