Summary: This study aimed to evaluate the survival rate, marginal bone levels, and full arch prosthetic success of short implants in severely resorbed and edentulous mandibles. A systematic review of three relevant studies found short-term dental implant survival rates ranging from 94.2% to 97.4% with a five-year follow-up, and prosthetic success rates around 62% during the same follow-up. The mean marginal bone level values of the affected short implants ranged from 0.2 mm to 0.6 mm. It was concluded that short dental implants positioned with precision as a full-arch fixed support are a valid therapeutic choice for medium-long-term rehabilitation of severe edentulous mandibular atrophy.

Summary: Finite element analysis was used to compare the effects of different implant lengths on atrophic mandibles with full-arch fixed prostheses. The study found that while longer implants generally showed better biomechanical behavior, 4 mm implants may also be a viable alternative for severely atrophic mandibles. Further research is needed to validate these findings.

Summary: Through analyzing 13 studies, results showed that the survival rate of fixed mandibular 3-implant retained prostheses was 95.43%, with an average prosthesis survival rate of 89.66% and a mean marginal bone loss of 1.09mm. The study suggests that the implant and prosthetic survival rates of this type of prosthesis are similar to those of full-arch mandibular prostheses retained by four or more implants. Further research is needed to explore the topic.

Summary: Comparing implant and prosthesis survival rates between full-arch immediate prostheses supported by four hydrophilic implants with bicortical anchorage and by five or six hydrophilic implants without bicortical anchorage, it was found that there were no significant differences in survival rates, but bicortical anchorage can improve the primary stability of implants.

Summary: The aim of this study was to evaluate the 5-year results of implants supporting fixed full-arch metal-ceramic restorations in patients who lost their teeth due to severe periodontal disease. The study found that the majority of implants with internal conical connection did not experience significant bone loss after 5 years. Abutment height and implant diameter were found to be associated with marginal bone level.

Summary: This study evaluated the accuracy of different laboratory scanners for scanning of implant-supported full arch fixed prosthesis with different implant angulations. The results showed that the 3ShapeE4 and Medit T710 scanners had the highest accuracy. These tested scanners can be used for scanning of All-on-four implant supported prosthesis.

Summary: The study found that patients interested in mandibular implant-supported complete denture are mainly influenced by their previous experience with mandibular complete dentures and dissatisfaction with retention.

Summary: This study used a three-dimensional finite element method to investigate the effects of changing bone atrophy and implant length on stress and strain in the surrounding bone of implants in all-on-four treatments. The results showed that stress and strain increased in models with moderate bone atrophy and low-density trabecular bone.

Summary: This study compared the three-dimensional (3D) deviations between full-arch digital scans and conventional implant impressions for edentulous maxillae and mandibles. The results showed that the deviations between the two methods were within the clinically acceptable threshold, and there was no significant difference in 3D deviations between maxillary and mandibular jaws.

Summary: The study aimed to analyze the behaviors of three intraoral scanners in full-arch scans, focusing on interdistance and axial inclination discrepancies. Six edentulous sample models were used, and reference data were obtained. The precision and trueness of interdistance measurements and axial inclinations were evaluated, and predictable errors were found.

Summary: The study characterized the physicochemical and mechanical properties of a milled fiber-reinforced composite for implant-supported fixed dental prostheses. Results showed that FDPs fabricated with milled epoxy resin matrix reinforced with glass fibers demonstrated high probability of survival at 300N load, indicating good fatigue performance.

Summary: This study evaluated the accuracy of different intraoral scanners (IOS) for scanning of implant-supported full arch fixed prosthesis with different implant angulations. The results showed that the type of scanner and the way the scanbodies are fixed significantly affect the accuracy. Scanning with Cerec Primescan scanner and fixed scanbodies resulted in more precise full arch implant scans.

Summary: This study evaluates the predictability of using CBCT alone for implant placement planning in edentulous patients. The findings indicate that digital planning by CBCT is insufficient to predict implant procedures and additional information and evaluation are required.
