Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry. The displacement of dental implants into the sinus membrane, a complication related to the maxillary sinus, is one of the most common accidents reported in the literature. The treatment for this complication is the surgical removal of the implant. A 60-year-old woman with three dental implants dis...

INTRODUCTION An important difference between natural teeth and dental implants is the fact that dental implants do not move in response to applied loads. As titanium implants do not have a periodontal ligament, intensive loads are transmitted and distributed to the adjacent bone. However, it is desirable in the implant-supported prosthesis that masticatory loads are distributed evenly. There is...

Dental implants have become an accepted treatment modality for aging patients with either completely or partially edentulous arches. However, growing patients with congenitally missing primary and/or permanent teeth often need dental implant treatment, even before puberty, for optimum functional and/or psychosocial development. From a developmental perspective, dental implants cannot accompany ...

objectives: the aim of this study was to compare the accuracy of dental implant impressions obtained by a combination of different impression techniques and viscosities of polyvinyl siloxane (pvs). materials and methods: four parallel fixtures were placed between mental foramina in a master model of lower dental arch. three different viscosities (putty/light body, medium body/light body, and mo...

High atomic number and density of dental implants leads to major problems at providing an accurate dose distribution in radiotherapy and contouring tumors and organs caused by the artifact in head and neck tumors. The limits and deficiencies of the algorithms using in the treatment planning systems can lead to large errors in dose calculation, and this may adversely affect the patient's treatme...

It is well known that the features of teeth in men and women can be changed with increasing age, in which some teeth could be damaged. Thus the dental-implants, which are implanted at the positions of damaged teeth to replace the latter, are developed and used widely in dentist medicine. At present, the dental-implants are, in general, manufactured by titanium materials. Clinic experiments show...
