AIM The purpose of this study is to evaluate the necessary number of pro-prosthetic interventions in view of the implanto-prosthetic rehabilitation of the defective prosthetic fields. MATERIALS AND METHODS We investigated a lot that included 230 patients aged between 18 and 82 who benefited from implant-prosthetic rehabilitation, the type of graft used, the types of membranes selected as well...

Background: Given that the world's population is aging, the problems associated with osteoporosis and related fractures are increasing. The aim of the study was to evaluate the effect of flaxseed extract on bone mineral density (BMD) in Wistar rats using digital radiography. Methods: In this experimental study, 25 male and 25 female Wistar rats were randomly divided into 5 groups: 1. Control...

In this study, a new approach involving placement and subsequent retrieval of titanium microimplants was employed for the histologic investigation of the implant-tissue interface in conjunction with maxillary sinus floor augmentation. Nine patients scheduled for sinus floor augmentation and simultaneous placement of Brånemark implants were included in the study. After a sinus graft procedure an...

A case of mandibular asymmetry is presented. It appears that in this patient the mandible was adapted to changes in the maxillary sinus area. Abnormal bone growth of unknown aetiology inside the sinus most likely caused complete remodelling in the maxillary sinuses and asymmetry of the mandible. Special tests used for detailed assessment of the patient supported the definitive diagnosis.

Sometimes, the severe superior maxillary atrophy compromises and even impide oral implants treatment. The use of rotatory instruments (drills) produce heat and lost of bone, but the osteotomes in implantology avoid this and simplifies the surgical treatment allowing implant installation with an easier technique. We present an expansive maxillary technique review, describing the main indications...

the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...

PURPOSE The purpose of this study was to histologically and immuno-histochemically evaluate tissue changes in the maxillary sinus after bone screw implantation and maxillary sinus augmentation using self-setting α-tricalcium phosphate (α-TCP; BIOPEX(®)-R) in rabbit. STUDY DESIGN Adult male Japanese white rabbits (n=15, 12-16 weeks, 2.5-3 kg) were used. The sinus lift was made from the nasal b...

Literature regarding the outcome of maxillary sinus floor elevation to create sufficient bone fraction to enable implant placement was systematically reviewed. Bone fraction and implant survival rate were assessed to determine whether grafting material or applied growth factor affected bone fraction. Trials where sinus floor elevations with autogenous bone (controls) were compared with autogeno...

Introduction: Cortical thickness, interradicular space width and bone density are key factors in the use of mini-implants as anchorage. Objective: This study assessed maxillary and mandibular alveolar and basal bone density in Hounsfield units (HU). Method: Eleven files with CT images of adults were used to obtain 660 measurements of bone density: alveolar (buccal and lingual cortical) bone, ca...
