OBJECTIVE Several theories have been presented to explain initial and secondary marginal bone loss around dental implants (e.g. microbial load, adverse loading, microbial leakage, compromised healing/adaptation of host-implant interface). MATERIAL AND METHODS This study compared the long-term outcome (up to 12 years) of sleeping with loaded implants in the mandible via a split-mouth concept. ...

Dental caries is one of the most common chronic childhood diseases and highly prevalent in world. The commonest treatment procedure for dental a restoration which aims to retain tooth. survival depends on factors associated with restorative materials, patients or operators. Thus, this study aimed determine reasons failure posterior primary teeth performed by undergraduate students. A total numb...

The aim of this study is to evaluate the effect of preheating on composite resins’ mechanical and physical properties. Preheating of composite resins positively affects the degree of conversion, viscosity, microleakage, marginal adaptation, microhardness and color change however, the flexural strength is adversely affected.  

AIM The purpose of this investigation was to evaluate the marginal adaptation of five root-end filling materials. METHODS AND MATERIALS Fifty human single-rooted teeth were resected 3 mm from the apex. Root-end cavities were then prepared using an ultrasonic tip and filled with one of the following materials: silver amalgam without zinc, white MTA-Angelus, white Portland cement (PC), Vitremer...

PURPOSE The primary goal of this stratified randomized controlled trial (SRCT) was to compare the stability of dental implants placed under three different loading regimens during the first 16 weeks of healing following implant placement. Implants were loaded immediately, early (6 weeks), or with conventional/delayed timing (12 weeks). Secondary outcomes were to compare marginal bone adaptation...

PURPOSE This study assessed the effect of preparation design on marginal adaptation and also compared the sensitivity and specificity of clinical evaluation techniques for marginal accuracy of cast restorations to stereomicroscopy. MATERIALS AND METHODS Three Ivorine molar teeth of different designs were prepared. (A)-A complete crown preparation with buccal shoulder and beveled finish line. ...

the biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (adscs) to repair peri-implan...

Background. It is important to understand the influence of different collar designs on peri-implant marginal bone loss, especially in the critical area. Objectives. The purpose of the present systematic review and meta-analysis was to compare dental implants with different collar surfaces, evaluating marginal bone loss and survival rates of implants. Methods. Eligibility criteria included clini...
