“…In clinical dentistry, implant-supported prostheses are the first option to consider for restoring edentulous areas because of their biocompatibility, predictable long-term results, and favorable mechanical properties [1]. The entire procedure involves substantial costs and complexity.…”

Objective: In response to the demand for dental implants, extensive research has been conducted on methods for transferring load to the surrounding bone. This study aimed to evaluate the stresses on the peripheral bone, implants, and prostheses under scenarios involving of the following variables: prosthesis designs, vertical bone heights, load angles, and restorative materials. Material and Methods: Three implants were inserted in the premolar and molar regions (5-6-7) of the two mandibular models. Model 1 represented 0 mm marginal bone loss and Model 2 simulated 3 mm bone loss. CAD/CAM-supported materials, hybrid ceramic (HC), resin-nano ceramic (RNC), lithium disilicate (LiSi), zirconia (Zr), and two prosthesis designs (splinted and non-splinted) were used for the implant-supported crowns. Forces were applied vertically (90°) to the central fossa and buccal cusps and obliquely (30°) to the buccal cusps only. The stresses were evaluated using a three-dimensional Finite Element Analysis. Results: Oblique loading resulted in the highest stress values. Of the four materials, RNC showed the low stress in the restoration, particularly in the marginal area. The use of different restorative materials did not affect stress distribution in the surrounding bone. The splinted prostheses generated lower stress magnitude on the bone, and while more stress on the implants were observed. Conclusion: In terms of the stress distribution on the peri-implant bone and implants, the use of different restorative materials is not important. Oblique loading resulted in higher stress values, and the splinted prosthesis design resulted in lower stress.

“…Another factor that reduces treatment time is the immediate or early loading of implants, that have been applied especially in cases of good bone quality, providing enhanced esthetics and function, with high implant survival rates. The insertion of a prosthesis within 72 hours of implant placement defines the immediate loading protocol [5] whereas when implants are put into function between 1 and 8 weeks after surgery, it defines early loading [6].The reduction of the healing period is not expected to result in increased marginal bone loss or implant failure, as reported in several studies [7,8].…”

Aim:The present split-mouth case report aims to describe the clinical and radiographic long-term outcomes of the implant rehabilitation of two mandibular premolars in which the digital workflow was used to apply different prosthetic protocols. Case description: A female 42-year-old patient with the absence of both mandibular second premolars was submitted to guided surgery for the placement of platform-switching Grand Morse connection implants. Digital workflow was used for implant and prosthetic planning, applying early loading protocol 21 days after surgery. The implant on the right side received the final abutment at the time of surgery (without loading), whereas the implant on the left side had a healing abutment placed, which was replaced by a temporary abutment and then by a final abutment. Two months after surgery, both implants had final ceramic restorations delivered. The patient was followed clinically and radiographically for 30 months, presenting excellent hard and soft tissue outcomes, with bone level changes lower than 2mm for both implants. Conclusion: The use of digital workflow and early loading, made the present implant-supported rehabilitation predictable, safe and time-efficient, resulting in total patient satisfaction. Peri-implant bone level was observed to be stable after early loading protocol for both platform-switching connection implants inserted, despite the prosthetic protocol applied.

“…Based on a didactic and general explanation, the term "biomechanics" can be defined as mechanics applied to biology, while mechanics is derived from the response of the structure to forces or displacements [1][2][3]. Biomechanical principles in implant dentistry remain as crucial as the clinical parameters that must be applied for oral rehabilitation.…”

“…Throughout the treatment plan phase, it is mandatory to consider how these forces, which will be applied to the dental implant, may be generated in terms of: type, direction, magnitude, duration and physiology [1][2][3][4][5][6]. According to the literature, the 5-year survival rates range from 97.1% -100% for fixed prostheses and 95% -100% for removable prostheses that are implant supported.…”

The rehabilitation of patients with dental implant-supported restorations is an ideal treatment option in contemporary dentistry. The aim of this review was to compile and to demonstrate the mechanical response during loading condition, on the stress distributions of implant-supported prostheses. The findings show that the majority of stresses were concentrated in the cervical region of the implant/abutment interface and that they can be affected by several clinical parameters and loading conditions. Finally, the final prosthetic design should combine superior mechanical response, long-term survival rate and allow patient satisfaction.
