Peri-implant bone level assessment of early loaded dental implants submitted to different prosthetic protocols: a case report

Abstract

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.

“…The replacement of missing teeth with dental implants is a well-documented and widely accepted treatment option known for its high success rate [ 1 , 2 , 3 ]. As patients’ aesthetic demands have increased, there has been a need for the development of new implant designs [ 4 ], advancements in surgical techniques [ 5 ], and improvements in prosthetic components [ 6 , 7 , 8 , 9 , 10 ].…”

“…Achieving precise adaptation between the abutment/implant and abutment/prosthesis is crucial for ensuring the long-term success of the dental treatment [ 9 , 10 ]. However, mechanical complications, such as screw loosening and fractures of screws, implants, or components, continue to be significant factors affecting implant therapy [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ].…”
