Use of BioGran and Calcitite in bone defects: histologic study in monkeys (Cebus apella).

Utilization of autogenous bone, bioactive glasses, and calcium phosphate cement in surgical mandibular bone defects in Cebus apella monkeys.

PURPOSE The purpose of the present study was to evaluate the histologic results of bone cavities that were surgically created in the mandibles of Cebus apella monkeys and filled with autogenous bone, PerioGlas, FillerBone, or Bone Source. MATERIALS AND METHODS Surgical cavities 5 mm in diameter were prepared through both mandibular cortices in the mandibular angle region. The cavities were ra...

Bone defect repair on the alveolar wall of the maxillary sinus using collagen membranes and temporal fascia: an experimental study in monkeys.

UNLABELLED Few studies has been done using guided bone regeneration in maxillary sinus defects. AIM To assess the bone repair process in surgical defects on the alveolar wall of the monkey maxillary sinus, which communicates with the sinus cavity, by using collagen membranes: Gen-derm--Genius Baumer, Pro-tape--Proline and autologous temporal fascia. MATERIALS AND METHODS In this prospective...

The Investigation of Prosocial Behavior in a Tool Task by Capuchin Monkeys (Cebus Apella)

Humans are exceptional in their willingness to and frequency with which they help one another. However, nonhuman primates also exhibit prosocial behavior. Recently, a number of laboratory studies examining prosociality among primates have yielded conflicting results. These contradictory findings may be due to a reliance on human interaction, tokens, or interactions in the direct context of food...

Ricinus communis biocompatibility histological study in the nose of Cebus apella monkeys Summary

Maxillary bone defect reconstruction using porous polyethylene implants.

PURPOSE The aim of this study was to evaluate the bone repair process in the maxillary sinus in monkeys treated with high-density porous polyethylene (Medpor) METHODS Four capuchin monkeys (Cebus apella) were submitted to bilateral horizontal osteotomies in the anterior wall of the maxillary sinus and divided into 2 groups: control group, left side with no implants, and porous polyethylene gr...
