“…From the 1960s to early 1980s, research on dental implants peaked. 3 Prior to this period, dental implants were mainly used to treat completely edentulous patients; 4 however, they were gradually used in the treatment of partially edentulous patients with fixed partial dentures supported by free-standing implants. 5 In 1986, Ericsson et al.…”

Background/purpose The three-unit bridge that combines a natural tooth and an implant provides extended treatment possibilities for partially edentulous patients. We conducted a systematic review and meta-analysis of clinical trials to evaluate three-unit porcelain-fused-to-metal (PFM) tooth-implant-supported prosthesis (TISP) compared with implant-supported-prosthesis (ISP) reconstruction outcomes and complications. Materials and methods The PubMed, Embase, and Cochrane library databases were searched for articles published before February 2021. The meta-analysis used a random-effects model to calculate overall effect size. The study was registered with PROSPERO (number: CRD 42021232606). Results Seven articles published between 2004 and 2015, with sample sizes ranging from 10 to 250 patients were included. No significant difference in the prosthesis failure rate, implant failure rate, prosthesis technical complication rate, implant technical complication rate, and marginal bone level change was observed between the TISP group and the ISP group. In TISP group, natural tooth failure rate was reported to range from 0% to 4.3%, biological complication related to the natural tooth was reported to range from 0% to 26.9%, and no trial reported natural tooth intrusion. Conclusion The three-unit short-span TISP is a potentially reliable treatment option for patients with missing posterior teeth.

“…Ceramics and carbon are biologically inert materials that were used as dental implants and tested for their physical, mechanical, chemical, and electrical differences. Focusing on inertness, thermal conductivity, modulus of elasticity, brittleness, and surface reactions to bond with the bone (1) . Presently, the yttriumstabilized tetragonal zirconia, which showed excellent mechanical and tribological properties altogether with biocompatibility is considered as the ceramic material of choice (2) .…”

Aims: This experimental study was conducted to evaluate the effect of β-calcium sulfate hemihydrate (CSH) as a bone graft substitute on the bone response around CAD/CAM machined zirconium dioxide (ZrO2) implants. Materials and methods: Forty ZrO2 implants were digitally designed and manufactured using computer-aided design/ computer aided-manufacturing CAD/CAM machine. Twenty New-Zealand rabbits were included in the experiment and a bed was made for implantation in each head of the left femur. Each animal received a ZrO2 implant in the mesial femoral head and this group of implants was considered as a control group. Then the calcium sulfate hemihydrate was placed in the implant bed at the distal femoral head followed by fixation of an implant, and this group was considered as an experimental group. The twenty rabbits were randomly allocated into four groups, to represent the study periods i.e. 3 days, 7days, 14 days, and 21 days. Bone response was assessed around each of the forty implants by measuring the bone mineral density using densitometric analysis of the digital periapical radiological image which was taken after the euthanization of the animals according to study intervals. Results: The results showed a statistically significant difference between the control group (ZrO2 implants) and the experimental group (ZrO2 implants with CSH) in bone mineral density. Conclusions: the use of CSH as an artificial bone graft around ZrO2 implant is beneficial for increasing bone formation around the implant as it increases bone density.

“…Tooth loss causes many problems such as loss of function, decreased masticatory efficacy, impaired aesthetic appearance and speech problems. Therefore, in modern dentistry, restoration and rehabilitation of edentulous cases become a necessity in avoiding mentioned conditions 1 . The treatment options for partially or totally edentulous patients range from removable or fixed partial denture and implant supported dentures 2 .…”

SummaryBackground/Aim: The objective of this study was to evaluate the stress distribution on implants and supporting bone tissue in All-on-Four and conventional designs in edentulous mandible by using 3D finite element analysis.Material and Methods: The different five models were designed according to All-on-Four concept and conventional implant placement designs. While the first two models were involved in All-on-Four concept with two long implants, the remaining models were designed by conventional approaches with three implants in different location and length. After the modelling procedures, a load of masticatory force was applied and the stresses were evaluated.Results: It has been observed that principal stresses in both cortical and spongious bone tissue were concentrated in models of All-on-Four design. Less principal stress levels were found in models of conventional design. Similarly, von Mises stress values on implant surfaces were found to be higher in All-on-Four concept.Conclusions: In severely resorbed mandible, the use of conventional implant placement is recommended. Although All-on-Four design seems to be a reasonable alternative for edentulous mandible, evidence-based results of this approach should be supported by long-term follow-up studies.
