BACKGROUND Long healing periods and submerged implant placement are commonly used in the maxilla. This extends the time of oral handicap and makes the use of immediate loading protocols an attractive option. The current clinical literature on direct loading of dental implants in the maxilla is limited. PURPOSE The purpose of this prospective clinical study was to evaluate the clinical outcome...

PURPOSE To study the clinical/radiographic outcomes and stability of a tapered implant design with a hydrophilic surface when placed in the maxilla using various protocols and followed for one year. METHODS Ninety-seven consecutive patients treated as part of daily routine in two clinics with 163 tapered implants in healed sites, in extraction sockets and together with bone augmentation proce...

PURPOSE The purpose of this study was to evaluate the efficacy of the ridge-splitting technique in the anterior maxilla, using piezoelectric surgery for immediate implant placement. Study outcomes were compared with those of implant placement in the same patients using the conventional drilling technique. MATERIALS AND METHODS Ten patients received a total of 22 implants in the anterior maxil...

PURPOSE Short implants often have the disadvantage of reduced primary stability. The present study was conducted to evaluate the feasibility and safety of a new expandable short dental implant system intended to increase primary stability. METHODS As a "proof of concept", a prospective clinical cohort study was designed to investigate intraoperative handling, primary and secondary implant sta...

AIM The aim of this study is to present 18 months follow-up results of porous tantalum trabecular metal-enhanced titanium dental implant (PTTM) in implant supported prosthesis in post-oncological patients. MATERIALS AND METHODS A total of 25 PTTM implants were placed in each jaw of 6 patients that met specific inclusion and exclusion criteria. Resonance Frequency Analysis (RFA) was conducted ...

BACKGROUND All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. M...

BACKGROUND/AIM Immediate loading is considered to be the most innovative technique in contemporary implant dentistry. Recent clinical and experimental findings have demonstrated that only implants with high primary stability can be subjected to immediate loading protocol with predictable results. It is generally accepted that the most important prerequsite for successful osseointegration is ach...

BACKGROUND Implant restorations have become a high predictable treatment option. Several caracteristics such as surgical technique and implant design can influence the treatment outcomes. The aim of the present study was to evaluate the influence of implant macro-design on primary stability measured with resonance frequency analysis (RFA) and insertion torque (IT). Material and Mehods: A total ...

Abstract Purpose This study investigated the effects of insertion speed dental implants on their stability. Methods Dental were inserted at speeds 4, 10, 20, and 30 rpm, respectively, into artificial bones two different bone qualities; namely, good (GB) poor (PB). Therefore, four qualities totaled eight groups, with five specimens per group. During process, maximum torque value (ITV) was measur...
