Full-Mouth Rehabilitation Using All-Ceramic Restorations.

The scientific and technological advancement of cosmetic dentistry has improved metal-free ceramic systems for fixed prosthodontics as well as porcelain veneers, making them an excellent treatment option for delivering superior cosmetic results. The authors present a clinical case of full-mouth rehabilitation using all-ceramic restorations with porcelain metal-free unit crowns in the maxilla, and porcelain veneers from the left inferior premolar to the right inferior premolar. Using this approach, they were able to achieve an excellent esthetic and functional result for the patient.

Utilization of ethyl cyanoacrylate and 2-octyl cyanoacrylate adhesives for autogenous bone graft fixation: histomorphometric study in rats.

The present study analyzes the repair process of autogenous bone graft in a block fixed with ethyl cyanoacrylate and 2-octyl cyanoacrylate adhesives in rat calvaria. Forty-eight rats, divided into 3 groups, received round osteotomies at the right parietal bone for the attainment of autogenous bone graft fragment, which was fixed at the opposite side to the donor site with ethyl cyanoacrylate (ethyl group) and 2-octyl cyanoacrylate (octyl group) adhesives. In the control group, bone fragment was only juxtaposed at the parietal bone surface without any fixation material.

Bone substitutes for peri-implant defects of postextraction implants.

Placement of implants in fresh sockets is an alternative to try to reduce physiological resorption of alveolar ridge after tooth extraction. This surgery can be used to preserve the bone architecture and also accelerate the restorative procedure. However, the diastasis observed between bone and implant may influence osseointegration.

Bone augmentation and autogenous transplantation of premolar to the site of the fissure in a cleft palate patient.

This article presents a case report of autogenous tooth transplantation to the site of the fissure, in addition to bone augmentation with graft of autogenous bone harvested from the iliac crest, performed in a cleft palate patient, who had insufficient bone volume. A non-syndromic 10-year-old girl, with a unilateral cleft lip and palate, incisal transforamen fissures, agenesis of the maxillary left central incisor and both maxillary lateral incisors, was treated with autogenous bone graft in the cleft area. The orthodontic treatment plan was to replace the missing lateral incisors with the maxillary canines and to extract the mandibular first premolars.

Mandibular rehabilitation using immediate implant loading after computer-guided surgery.

Computed tomographic scan is a precise complementary examination of diagnostic imaging and a noninvasive surveying technique that enables the professional to improve precision of implant placement by building a prototype that allows the confection of surgical guides. The authors present a clinical case of mandible rehabilitation based on computed tomography of a patient; the cross sections were reformatted and used to construct a virtual planning of the implants and a guide template in Dental Slice. Immediate loading of 5 titanium implants were placed in the mandible using a Slice Guide System.

Evaluation of the bone healing process utilizing platelet-rich plasma activated by thrombin and calcium chloride: a histologic study in rabbit calvaria.

To evaluate the bone healing of defects filled with particulate bone graft in combination with platelet-rich plasma (PRP), added with a mixture of calcium chloride and thrombin or just calcium chloride. Two 5-mm bone defects were created in the calvaria of 24 rabbits. Each defect was filled with particulate bone graft and PRP.
