Antimicrobial Efficacy of Materials Used for Sealing the Implant Abutment Screw Hole: An In Vitro Evaluation
Aim:
The aim of this in vitro study was to assess the antimicrobial efficacy of materials (gutta percha [GP], polytetrafluoroethylene [PTFE] tape, and vinyl polysiloxane [VP]) used for sealing the implant abutment screw hole (IASH).
Methods:
Sixty implants with a Morse cone connection were used. The implants were randomly divided into 3 groups (20 implants/group). In groups 1, 2, and 3, the IASH was sealed with GP, PTFE, and VP, respectively. Unstimulated whole saliva (UWS) was used as a contaminant medium for the incubation of the specimens. After 7 days of incubation, the specimens were opened under aseptic conditio...

Impact of Inorganic Xenograft on Bone Healing and Osseointegration: An Experimental Study in Rabbits
Purpose:
To evaluate if an inorganic graft applied before implant insertion interferes with osseointegration.
Materials and Methods:
The bilateral mandibular incisors of 12 rabbits were extracted. One of the sockets was randomly filled with an inorganic xenogenic bone graft, whereas the remaining socket was allowed to heal naturally and served as a control. After 60 days, titanium implants were inserted into healing areas. The animals were killed 60 days after. Bone depositions were marked with fluorochrome oxytetracycline, alizarin, and calcein and evaluated using confocal laser scanning microscopy. Bone-to-implant c...

Prognostic Classification System for Implant Recession Defects
Conclusions:
Severity and number of these contributing factors should be considered before implant placement and/or in the treatment of periimplant defects to achieve the best esthetic and functional outcome. In addition, assessment of prognostic factors should be used to provide the patient a realistic, long-term assessment of the esthetic and functional stability of both implant and the surrounding periimplant tissues.

Comparative Study on Early Osseointegration of Implants According to Various Drilling Speeds in the Mandible of Dogs
This study evaluated the effect of drilling speed on early bone healing in the mandible of dogs.
Material and Methods:
Six dogs were selected, and mandibular premolars and molars were extracted. After 2 months, 3 hydroxyapatite-surfaced fixtures were implanted with drilling speeds of 50, 800, and 1200 rpm on the right side first and then on the left side after 2 weeks. Implant stability quotient (ISQ) was measured on insertion, after 2 and 4 weeks.
Results:
Based on the ISQ measurement, the 1200-rpm group showed a higher value than the 50-rpm group at 2 weeks and 4 weeks (P (Source: Implant Dentistry)

Ridge Preservation After Maxillary Third Molar Extraction Using 30% Porosity PLGA/HA/β-TCP Scaffolds With and Without Simvastatin: A Pilot Randomized Controlled Clinical Trial
Objective:
To evaluate clinically and radiographically, in humans, the healing of maxillary third molars postextraction sockets after application of different ridge preservation techniques 3 months after tooth extraction.
Materials and Methods:
Twenty-six sockets (13 patients) were randomly assigned to 4 treatment modalities: deproteinized bovine bone mineral with 10% collagen (DBBM-C), poly(D,L-lactide-co-glycolide) with hydroxyapatite/β-TCP scaffold (PLGA/HA), PLGA/HA/β-TCP with 2.0% simvastatin scaffold (PLGA/HA/S), and spontaneous healing (control). Clinical complications were assessed, and cone-beam computed to...

Bone Resorption During Submerged Healing After Guided Bone Regeneration: A Prospective Case Series
Objective:
The aim of this study was to evaluate bone resorption quantitatively during the healing period subsequent to ridge augmentation.
Materials and Methods:
Sixteen patients requiring vertical ridge augmentation before implant placement were recruited in the study. The study used an allograft and nonresorbable membrane.
