Mechanical behavior of provisional implant prosthetic abutments

Abstract

Introduction: Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization. Objectives: In vitro testing of strength and deformation of implant prosthetic abutments made from different materials (Titanium/PEEK/methacrylate). Material and Methods: Forty Sweden&Martina® implant prosthetic abutments (n=40) were divided into five groups: Group MP: methacrylate provisional abutments with machined titanium base; Group PP: Poly ether ether ketone (PEEK) provisional abutments; Group TP: titanium provisional abutments; Group TAD: titanium anti-rotational definitive abutments; Group TRD: titanium rotational definitive abutments. Their mechanical behavior under static loading was analyzed. Samples were examined under a microscope to determine the type of fracture produced. Results and Conclusions: Definitive anti-rotational titanium abutments and definitive rotational titanium abutments achieved the best mean compression strength, while PEEK resin provisional abutments obtained the lowest. The group that showed the greatest elastic deformation was the group of titanium provisional abutments. Key words:Immediate loading, immediate provisionalization, implant prosthetic abutment, definitive implant prosthetic abutment.

In Vitro Fit and Cementation Resistance of Provisional Crowns for Single Implant-Supported Restorations

“…Provisional prostheses should be the prototype of the final prostheses made from a material able to be repaired or partially prepared for necessary corrections after installation in the mouth (3). For successful provisional prostheses, knowledge of different materials and products available on the market is necessary to optimize the survival rate in use (4).…”

PEEK materials as an alternative to titanium in dental implants: A systematic review

“…Finally, 54 articles were included in present systematic review. Detailed data of the incorporated studies are listed as: 36 invitro studies in Table and 18 invivo studies in Table on PEEK material to find its efficacy as dental implant material .…”

Influence of Biologically Oriented Preparation Technique on Peri-Implant Tissues; Prospective Randomized Clinical Trial with Three-Year Follow-Up. Part I: Hard Tissues

“…Callan et al [26]; Patri et al [27]; Peñarrocha-Diago et al [28]; Agustín-Panadero et al [3]; Canullo et al [24], and Marconcini et al [29]. Bone loss measurement used Rhinoceros software, as in an earlier study by Agustín-Panadero et al [3].…”

“…Callan et al [26]; Patri et al [27]; Peñarrocha-Diago et al [28]; Agustín-Panadero et al [3]; Canullo et al [24], and Marconcini et al [29]. Bone loss measurement used Rhinoceros software, as in an earlier study by Agustín-Panadero et al [3]. The software processes the images captured after calibrating the radiographs as described by Piao et al [30]; Peñarrocha-Diago et al [28]; Spinato et al [31]; and Agustín-Panadero et al [32], who used various software tools with the same objective as the present trial.…”

“…Rehabilitation with dental implants has become a frequently used procedure enjoying high success rates of between 90% and 95% after ten yeas [1][2][3]. Among the many factors that influence implant survival are the patient's health status, the characteristics of the host site, and the surgical technique employed [4][5][6][7][8].…”
