One-Piece Monolithic Zirconia Single Tooth Implant-Supported Restorations in the Posterior Region: A 1-Year Prospective Case Series Study.

Objective: To assess the clinical, radiographic and patient-reported outcome measures, and the success of screw-retained one-piece monolithic zirconia implant-supported restorations in the posterior region during a 1-year follow-up.

Methods: In a prospective case series, 50 single molar sites in the posterior region of 41 patients with a minimum age of 18 years and sufficient bone volume for placing an implant (≥ 8 mm) and space for an anatomical restoration were included. Following prosthetic-driven digital three-dimensional treatment planning, a tissue-level implant with an internal connection was inserted during a one-stage surgical procedure.

Accuracy of augmented reality navigated surgery for placement of zygomatic implants: a human cadaver study.

Purpose: Placement of zygomatic implants in the most optimal prosthetic position is considered challenging due to limited bone mass of the zygoma, limited visibility, length of the drilling path and proximity to critical anatomical structures. Augmented reality (AR) navigation can eliminate some of the disadvantages of surgical guides and conventional surgical navigation, while potentially improving accuracy. In this human cadaver study, we evaluated a developed AR navigation approach for placement of zygomatic implants after total maxillectomy.

Metal-Free Custom-Made Zirconia Implants-A Prospective 5-Year Follow-Up Single-Arm Clinical Trial.

Background: Dental implants made of zirconia (ZrO) are a potential alternative for titanium implants in dentistry because of their good biocompatibility, mechanical properties and excellent aesthetic results. However, solid long-term scientific data to prove clinical success of ZrO implants are scarce.

Aim: The aim of this study was to describe and to examine the clinical performance of custom-made two-piece ZrO implants, to identify possible influencing factors: a) manipulation of the implant after placement and b) the occlusal scheme on the survival rate, and to evaluate the performance of the implant-supported crown.

Outcomes of implants placed in sites of previously failed implants: a systematic review and meta-analysis.

The survival rate of implants placed at sites of previous failures including the best treatment strategies remain unclear. This systematic review was performed to assess implant survival and peri-implant health for such cases, including subgroup analyses of immediate versus delayed implant placement and augmentation. Four electronic databases were searched.

Analysis of 8.5 mm Long Dental Implants Provided with Splinted or Solitary Implant Restorations: A 15-Year Prospective Study.

The long-term effects of implant properties, such as implant length, platform switch, and crown splinting, on peri-implant health require more investigation. Therefore, the aim was to assess the long-term peri-implant health and patient satisfaction in a patient cohort, obtained from two prospective randomized controlled trials, who received 8.5 mm long dental implants, with either splinted or solitary suprastructures and with or without a platform switch, over a period of 15 years.
