This clinical study was done to compare between digital with conventional impression used in the CAD/CAM constructed 4- implant supported mandibular overdenture base regarding their effect on the bone height changes
This study aims to evaluate retention ,chewing efficiency and masticatory performance of flexible versus CAD/CAM partial dentures opposing to fixed implant retained restorations.
Thirty maxillary edentulous patients with previous mandibular All-on-4 screw retained prosthesis and their age ranged from 55 to 65 years were selected from the outpatient clinic, of prosthodontics Department, Faculty of Dentistry, Mansoura University from March 2022 to July2022 and 80% power was used to calculate patients sample according to the results of a previous study 1 which showed no significant difference was reported when comparing occlusal stability ,implant stability and periimplant soft tissue changes between different implants angulation of both groups. (Effect size=.70mm and α=.05). The power analysis was performed using the G*Power program (version 3.1.5, Kiel, Germany)
The study aims to compare implant stabilities between immediate and early loaded, immediately placed bone-level tapered dental implants in the upper jaw in the partial and total edentulous patients assessing marginal bone loss, oral health-related quality of life, and patient satisfaction within one, two and five years of follow-ups.
Objectives: evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures. There were two groups : 1) The control group 2) The study group
Few previous studies have employed HA in the implant socket; instead, the majority have applied it topically to the area around dental implants after they have been placed. The application was done after suturing in these investigations. Therefore, the goal of the current study was to inject HA into the implant socket and onto the alveolar bone prior to implant insertion and suturing in order to preserve the HA for an extended period of time. This study aims to use a visual analog scale (VAS) on the first, third, and tenth days following the surgical intervention to assess the efficacy of employing HA in dental implants in terms of pain reduction that may accompany dental implant surgery.
dental implants are usually placed by sequential set of drills which could increase the time of the surgery and could raise the temperature of the osteotomy preparation so a new drill was designed to place the implants fast and easy way
Since the beginning of the implant dentistry, a large variety of materials have been used for restoring single or multiple implants, such as gold, titanium, alumina (Al2O3), and zirconia (ZrO2). Patient physical and esthetic requirements play one of the most important role in making decisions related to which material should be chosen. In fact, long-term stability, compatibility with oral tissues esthetics and costs should be considered. Several studies demonstrated that both titanium and zirconia have an excellent biocompatibility and long-term stability even though something could change in terms of esthetic outcomes. Related to esthetics, the color of the peri-implant mucosa is an essential factor that clinicians have to take in to account. Unfortunately, discoloration of peri-implant mucosa sometimes happens. Some authors hypothesized that titanium abutments could provoke a grayish appearance of the mucosa, and, in order to avoid this problem, other authors suggested to perform augmentation of the peri-implant soft tissue thickness in the esthetic area. A study on pig maxillae found that the type of abutment or crown material and the mucosa thickness have significant influences on color changes of the mucosa. Titanium induced the most prominent color change, and, in patients with thinner mucosa, zirconia induced the least noticeable color changes. Nowadays, to reliably evaluate differences in color in implantology, the most used method is spectrophotometry, due to the capacity of detecting even small color differences and due to the higher reproducibility. Several investigations on pig jaws using spectrophotometric measurements were carried out recently, with the aim of investigating the color changes. It was found that generally titanium abutment lead to a more pronounced discoloration; however, gingival thickness greater than 2 mm did not reveal any difference related to the type of abutments. In addition, an increase in mucosal thickness might minimize the discoloration. The only study on human patients revealed that the color of the peri-implant mucosa presents more dark, green and blue components compared to the natural gingiva. Soft tissue thickness appeared a crucial factor with respect to the spectrophotometrically measured degree of peri-implant mucosal discoloration, with a trend for less pronounced discolorations in patients with thick mucosa. Furthermore, the authors found that peri-implant mucosa was on average 0,5-0,7 mm thicker than natural gingiva. However, this study evaluated the thickness of the gingiva by means of CBCT, which could lead to some errors due to the superimposition of the lips and cheeks, as well as the tongue that occupies the most space of the oral cavity. Moreover, esthetics were evaluated by clinicians visually at a specific distance asking them if discoloration was visible or not visible. Furthermore, no questionnaire was given to patients to evaluate esthetics neither discomfort while brushing. Therefore, The objective of this cross-sectional study is to evaluate the influence of gingival thickness (GT) upon mucosal color (MC) around dental implants measured spectrophotometrically. A secondary goal is to evaluate the correlation between mucosal color changes and type of abutment material around dental implants.
The aim of the present study was to compare the initial healing and long term performance of narrow diameter implants in patients with uncontrolled Diabetes mellitus type 2 (T2DM) and healthy individuals.
