Alveolar Bone Resorption Evaluation Around Single-piece Designed Bicortical Implants, Using Immediate Loading Protocol, Based on Orthopantomographs

Abstract

Background:Inserting dental implants in severely atrophied jawbones is a great challenge for the dental practitioner. There are an increasing number of patients who choose dental implantanchored prosthetic restorations despite compromised bone quality and quantity. There have been numerous attempts in adapting implant design for the atrophic crestal bone. One-piece, needle-type basal implant design is a typical design for these cases. These implants are inserted in the remaining compact bone located in the basal aspect of the jawbones. If high primary stability is achieved, these implants are used for immediate loading protocol. From many points of view, this technique is based on contradictory principles compared to classic implant surgery and loading protocols. Theaimof this study was to investigate the long-term success of basal one-piece short-diameter dental implants used for immediate loading protocol.Materials and methods:A total of 56 dental implants were included in this study. Peri-implant bone loss was measured on orthopantomographs. Bone resorption was measured in millimeters in the first 6 and 12 months of functional loading.Results:There were no failing implants in this period; average bone resorption was 1.59 mm after 6 months of functional loading and 2.05 mm after 12 months. Bone resorption was slightly higher in the mandible than in the maxilla.Conclusions:Immediate implant loading protocol might be an attractive solution for fixed fullarch restoration using short-diameter one-stage basal implants, but long-term effects require further investigations.

Allogeneic Demineralized Dentin Matrix Graft for Guided Bone Regeneration in Dental Implants

“…Regarding the maxilla and mandible, maxillary BMB height showed more resorption than that of the mandible during both the initial and functional periods. However, Szava et al reported that implants placed in the maxilla showed less bone loss than implants placed in the mandible after 1-year loading [35]. This result suggests that there are differences in remodeling procedures after GBR between the maxilla and mandible, and there may be greater volumetric shrinkage in the maxilla than in the mandible.…”

Fracture Resistance and Finite Element Analysis of Single-piece PEEK Implant Restorative System Versus Titanium Single-piece Implant Restorative System: In-vitro Study

“…Among the advantages is the absence of microgaps between the implant platform and abutment, reducing vertical bone loss, which may occur at a slower rate with one-piece implants. [19][20][21] Furthermore, they could be used in restoring minimal edentulous spaces, and they allow for minimally invasive surgical procedures that foster improved soft tissue adhesion. 22 Numerous studies have explored the load distribution in one-piece and two-piece implants.…”
