Micro structure is the microscopic surface topography of an implant. In simple terms, is it smooth or is it rough. The rougher the surface, the better. A roughened surface is directly associated with higher implant survival rates (Figure 1) [2]. Micro structure has a direct effect on the osseointegrative process and therefore most important in the long term stability of an implant after healing...

Nowadays, artificial implants, a third denture of human, can maximize the chewing efficiency of patients with missing teeth, delay the absorption of alveolar bone and improve the quality of life. Osseointegration of the interface between the bone and implants, introduced first by Branemark et al. [1,2], is the most determining factor in oral clinical implant applications. As the main material i...

The titanium implant surface was sandblasted with large grits and acid etched (SLA) to increase the implant surface for osseointegration. The topography of the titanium surface was investigated with scanning electron microscopy (SEM) and a profilometer. The SLA implant demonstrated uniform small micro pits (1-2 microm in diameter). The values of average roughness (R(a)) and maximum height (R(t)...

The surface of an implant determines its ultimate ability to integrate into the surrounding tissue. The composite effect of surface energy, composition, roughness, and topography plays a major role during the initial phases of the biological response to the implant, such as protein adsorption and cellular adherence, as well as during the later and more chronic phases of the response. For bone, ...

Objective: The objective of this narrative is to review the significant biomechanical aspects implant systems, describing stresses and strains associated with their functional roles in oral rehabilitations.

the maxillofacial region is one of the most injury-prone areas during road traffic accidents, personal violence, falls and sports. maxillofacial trauma can lead to breakage or avulsion of upper anterior teeth, which may cause significant aesthetic and functional problems. there are many treatment options available for rehabilitation including removable partial dentures, fixed partial dentures, ...

Implant-guided surgery using a surgical template was introduced for prosthetic-driven implant placement. In the case of partially edentulous patient, guide is created to fit patient's tissue by overlaying cone-beam computed tomography (CBCT) scan data on optical obtained scanning model or actual oral cavity. patients, because there are no teeth, radiographic denture manufactured, and 'dual CBCT...

PURPOSE The present study was performed to evaluate the effect of erbium:yttrium-aluminium-garnet (Er:YAG) laser irradiation on the change of hydroxyapatite (HA)-coated implant surface microstructure according to the laser energy and the application time. METHODS The implant surface was irradiated by Er:YAG laser under combination condition using the laser energy of 100 mJ/pulse, 140 mJ/pulse...

Objectives: Prosthodontic rehabilitation using dental implants has become a common practice in dentistry at the present time. Although severe complications related to dental osseointegrated implants are uncommon, in recent years several cases of oral squamous cell carcinoma adjacent to dental implants have been published. Study Design: A 67-year-old edentulous woman developed an oral squamous c...
