The present retrospective analysis resulted in a 10-year implant survival rate of 98.8% and a success rate of 97.0%. In addition, the prevalence of peri-implantitis in this large cohort of orally healthy patients was low with 1.8% during the 10-year period.

This prospective cross-sectional study demonstrates stable peri-implant hard and soft tissues for all 41 implants examined and satisfactory esthetic outcomes overall. The follow-up of 5 to 9 years confirmed again that the risk for mucosal recession is low with early implant placement. In addition, contour augmentation with guided bone regeneration was able to establish and maintain a facial bone wall in 95% of patients.

This prospective study evaluates the concept of early implant placement and demonstrated successful tissue integration for all 20 implants and stable bone-crest levels around implant-abutment interfaces according to the platform-switching concept. The midterm 3-year follow-up revealed pleasing esthetic outcomes and stable facial soft tissues. The risk of mucosal recession was low, with only one patient showing minor recession of the facial mucosa. These encouraging results need to be confirmed with a 5-year follow-up examination.

After a mean exposure time of 10.75 years, high survival rates for reconstructions supported by Sand-blasted Large-grit Acid-etched implants can be expected. Ceramic chipping was the most frequent complication and was increased in dentitions with attrition and in FDPs compared with SCs.

A fixed dental prosthesis can be secured to an endosseous implant via cementation (using a provisional or definitive cement) on an implant abutment that is screw retained to the implant or directly in the implant via screw retention. The clinical decision as to which retention system best suits the individual patient depends on several factors. The aim of this review is to present a detailed overview of the factors potentially influencing whether to choose screw retention or cement retention. These factors include the individual indication, advantages and disadvantages of the different retention mechanisms, the retention provided, retrievability, provisionalization, esthetics and clinical performance, including failures and complications. The results of recently published systematic reviews on this topic are discussed and an overview is provided. A decision tree is presented to facilitate the clinical selection of the retention type. This overview concludes that the choice of retention type (screw retained or cement retained) might not influence the overall survival of the implant-supported fixed dental prosthesis, but may be responsible for the development of certain complications. The decision may depend on technical feasibility and on weighing the pros and cons.

Digital protocols increasingly influencing prosthetic treatment concepts. Implantsupported single-unit and short-span reconstructions will benefit most from the present digital trend. Monolithic implant crowns connected to pre-fabricated titanium abutments starting with IOS and combined with virtual design and production without any physical master casts have to be considered in place of conventional manufacturing in posterior sites. Subsequently, no space for storage is needed in the complete digital workflow, and in case of renewal, a copy of the formerly reconstruction can be fast and inexpensively produced by means of rapid prototyping. The technological progress is split in subtractive methods, as milling or laser ablation, and additive processing, as 3D printing and selective laser melting, respectively. Individualized supra-implant soft tissue architecture can be calculated in advance according to a morphologic copy. All these technologies have to be considered before implementing new digital dental workflows in daily routine. The correct indication and application are a prerequisite and crucial for the success of the overall therapy, and finally, for a satisfied patient. This includes a teamwork approach and equally affects the clinician, the dental assistance, and the technician as well.The digitization process will change the entire dental profession. Major benefits will arise to reduce production costs, improve time-efficiency, and to satisfy patientsÕ perceptions of a modernized treatment concept.
