To evaluate how peri-implant hard and soft tissue height (BH, MH) alter after final prostheses placement related to labial hard and soft tissue thickness (BW, MW). Forty-five platform-switched implants were classified into four groups according to BW and MW: type 1 (thick BW and thick MW), type 2 (thick BW and thin MW), type 3 (thin BW and thick MW), type 4 (thin BW and thin MW). Tissue resorption

Zygoma implant under function: biomechanical principles clarified Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-06-22 Edmond Bedrossian, John Brunski, Bilal Al-Nawas, Peer W. Kämmerer
The purpose of this document is to clarify the biomechanical principles involved when zygoma implants are placed under functional loads. Two independent reviewers conducted electronic search of the literature from January 2000 to February 2023 describing the biomechanical principles involved using the zygoma implant for maxillary reconstruction. Articles describing the stresses within the zygoma implant

Investigating the implant position reproducibility of optical impressions obtained using an intraoral scanner and 3D-printed models fabricated using an intraoral scanner Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-06-21 Maya Iwamoto, Wataru Atsuta, Yasuhide Kaneko, Junnosuke Ito, Takeshi Kanno, Takahiro Murakami, Jyoji Tanaka
This study aims to examine the effect of the size of the intraoral scanning area on implant position reproducibility and compare the implant position reproducibility of plaster models fabricated using the silicone impression technique, the digital model of an intraoral scanner, and three-dimensional (3D)-printed models fabricated using an intraoral scanner. Scanbodies were attached to an edentulous

Three-dimensional changes of a porcine collagen matrix and free gingival grafts for soft tissue augmentation to increase the width of keratinized tissue around dental implants: a randomized controlled clinical study Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-06-16 Ramanauskaite Ausra, Obreja Karina, Müller Katharina, Schliephake Carla, Wieland Johanna, Begic Amira, Dahmer Iulia, Parvini Puria, Schwarz Frank
Emerging clinical data points to the relevance of the presence of keratinized tissue (KT). Although apically positioned flap/vestibuloplasty along with free gingival graft (FGG) is considered as a standard intervention for augmenting KT, substitute materials appear to be a viable treatment alternative. So far, there is a lack of data investigating the dimensional changes at implant sites treated with

Autonomous robotic surgery for zygomatic implant placement and immediately loaded implant-supported full-arch prosthesis: a preliminary research Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-05-19 Changjian Li, Menglin Wang, Huanze Deng, Shumao Li, Xinyu Fang, Yijie Liang, Xihua Ma, Yue Zhang, Yanfeng Li
A patient with extensive atrophy of the alveolar ridge in the posterior portion of the maxilla was selected to complete an experimental and clinical case of the robotic zygomatic implant to investigate the viability of an implant robotic system in clinical use. The preoperative digital information was collected, and the implantation position and personalized optimization marks needed for robot surgery

Evaluation of surgical techniques in survival rate and complications of zygomatic implants for the rehabilitation of the atrophic edentulous maxilla: a systematic review Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-05-17 Peer W. Kämmerer, Shengchi Fan, Carlos Aparicio, Edmond Bedrossian, Rubén Davó, Dean Morton, Gerry M. Raghoebar, Sepehr Zarrine, Bilal Al-Nawas
To assess the outcome [zygomatic implant (ZI) survival] and complications of the original surgical technique (OST) and an Anatomy-Guided approach (AGA) in the placement of ZI in patients with severely atrophic maxillae. Two independent reviewers conducted an electronic literature search from January 2000 to August 2022. The inclusion criteria were articles reporting at least five patients with severely

The efficacy of a porcine collagen matrix in keratinized mucosa width augmentation: a 10-year follow-up clinical prospective study Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-04-12 Mattia Manfredini, Pier Paolo Poli, Pierluigi Guerrieri, Mario Beretta, Carlo Maiorana
The aim of the present study was to evaluate the long-term effectiveness of a xenogeneic collagen matrix (CM) in pre-prosthetic augmentation of the keratinized mucosa width (KMW) at implant sites. All of the patients with localized implant-supported rehabilitation previously treated with vestibuloplasty and KMW augmentation with a non-cross-linked porcine CM were recalled. KMW was measured clinically

Virtual pterygoid implant planning in maxillary atrophic patients: prosthetic-driven planning and evaluation Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-03-27 Yuanyuan Sun, Chunfeng Xu, Ningtao Wang, Yiqun Wu, Yuelian Liu, Shengchi Fan, Feng Wang
The study aims to use cone beam computed tomography (CBCT) to (1) define the virtual valid length of pterygoid implants in maxillary atrophic patients from the prosthetic prioritized driven position and (2) measure the implant length engaged in the pterygoid process according to the HU difference of the pterygoid maxillary junction. Virtual pterygoid implants were planned with CBCT of maxillary atrophic

Preload and friction in an implant–abutment–screw complex including a carbon-coated titanium alloy abutment screw: an in vitro study Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-03-22 K. Sagheb, C.-I. Görgen, S. Döll, I. Schmidtmann, S. Wentaschek
An experimental approach was designed to measure the preload force, the coefficient of friction and the component of the tightening torque that is needed to surmount the thread-friction in an implant–abutment–screw complex that includes a carbon-coated screw. With the determined preload values the coefficient of friction was calculated. 25 unused complexes, containing an implant, an abutment and a

Is one-stage lateral sinus lift and implantation safe in severely atrophic maxillae? Results of a comparative pilot study Int. J. Implant Dent. (IF 2.7) Pub Date : 2023-02-19 Sascha Virnik, Laura Cueni, Anita Kloss-Brandstätter
The aim of this retrospective comparative study was to evaluate the survival of dental implants placed in the posterior maxilla with a residual bone height less than 3 mm using a one-stage lateral sinus lifting approach. The research question was whether in very severely atrophied maxillary bones (residual height < 3 mm), a sinus lift with simultaneous implant placement would be associated with a higher
