Connective tissue graft wall technique for mandibular Class II furcation defects: Two case reports

Clinical Advances in Periodontics, EarlyView.
Abstract Background Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to limited accessibility and the progressive interradicular attachment loss that compromises long‐term tooth stability. Deep periodontal pockets in molars and premolars often present as combined defects, including horizontal FI ...

Subperiosteal circumferential connective tissue graft for vertical implant soft tissue augmentation

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertical implant soft tissue augmentation is indicated to optimize esthetic outcomes in cases of peri‐implant soft tissue deficiency or dehiscence, particularly when the peri‐implant mucosa is exposed during a full smile. This manuscript describes the use of a subperiosteal circumferential connective tissue graft (SC CTG) for ...

Guided bone regeneration using CAD‐CAM zirconia barriers: A case series with digital evaluation of bone changes

Clinical Advances in Periodontics, EarlyView.
Background CAD/CAM zirconia barriers represent an advanced option for guided bone regeneration (GBR) in three‐dimensional defects, integrating mechanical stability, biocompatibility, and digital precision. The objectives of this case series were to evaluate, clinically, histologically, and three‐dimensionally, the use of customized zirconia barriers ...

Effect of Diamond Bur Grit Size on Composite Repair.

The journal of adhesive dentistry, 2015
This study investigated the effect of diamond bur grit size on the repair bond strength of fresh and aged resin composites.Blocks of microhybrid composite (Opallis, FGM) were stored in distilled water at 37°C for 24 h (fresh composite) or subjected to 5000 thermal cycles (aged composite).

Cutting characteristics of dental diamond burs made with CVD technology [PDF]

Brazilian Oral Research, 2006
The aim of this study was to determine the cutting ability of chemical vapor deposition (CVD) diamond burs coupled to an ultrasonic dental unit handpiece for minimally invasive cavity preparation. One standard cavity was prepared on the mesial and distal surfaces of 40 extracted human third molars either with cylindrical or with spherical CVD burs. The

Gradient layers of boron doped diamond on titanium substrates

, 2007
For the deposition of well-adhesive, low-doped diamond layers on titanium substrates a gradient layer is designed. At first a highly boron-doped diamond layer is deposited, which shows good adhesion to the titanium substrate, followed by a low-boron ...

Viability of Tumor Cells in Bone Dust: Implications for Oncologic Skull Base Surgery

Head &Neck, EarlyView.
ABSTRACT Background Head and neck tumors with skull base involvement may require drilling of tumor infiltrated bone. We hypothesize that bone dust generated during this process contains viable tumor cells that may seed the surgical field. Methods Tumors with gross bone invasion were drilled, and dust was collected for H&E, cell viability analysis, and ...
