LITERATURE REVIEW Planning for Immediate Loading of Implant-Supported Prostheses: Literature Review Juliana Aparecida Delben, DDS, MSc* Marcelo Coelho Goiato, DDS, MSc, PhD Eduardo Piza Pellizzer, DDS, MSc, PhD Osvaldo Magro Filho, DDS, MSc, PhD The aim of this study was to present the factors that influence planning for immediate loading of implants through a literature review for treatment success. Research was conducted in the PubMed database including the key words immediate implant loading, implant-supported prostheses, and implant planning for studies published from 2000 to 2011. Forty-eight articles were used in this review to describe the indications and counterindications, presurgical planning, and technologies available for planning of this treatment alternative. Key Words: dental implant, implant-supported prosthesis, immediate loading INTRODUCTION he evolution of dentistry increased the use of osseointegrated implants as a treatment alternative for rehabilitation of multiple or single edentulous areas.1–3 According to the conventional protocol, a healing period of 3 to 6 months without loading is necessary after implant placement to allow osseointegration without formation of fibrous tissue.4–6 After this period, a new surgical procedure is carried out to insert healing caps previously to the prosthesis fabrication.5 However, considering the need to reduce the time for treatment,4 the original protocol was replaced by the 1-step surgical technique1,7 and immediate loading with provisional or final restorations.8,9 According to Schiroli3 and Bilhan et al,10 the immediate loading of implants is a safe procedure with success rates higher than 90%. Some studies11,12 demonstrated that several factors are important to enhance treatment success, such as primary stability of the implant, splinting for ˜ Sao Paulo State University, Aracatuba Dental School, Brazil. ¸ * Corresponding author, e-mail: DOI: 10.1563/AAID-JOI-D-10-00188 T multiple rehabilitations, reduction of mechanical loading, and fabrication of stable restorations to avoid displacement or removal of the implant. In addition, it is important to obtain adequate positioning of the implant, healing of the soft and bone tissues, and adequate function and esthetics with 1 surgical step.13 So the success of the immediate loading of implants depends on accurate planning to evaluate bone quality and quantity as well as the biomechanics to reveal alterations that may counterindicate the procedure.10 Furthermore, the planning should be prosthetically driven to restore comfort, function, and esthetics. According to this, although radiographic examinations associated with diagnostic waxing have been widely used for planning of treatment with implants,14 recent technologies are available to increase the accuracy and safety for planning and insertion of implants, such as computerized tomography (CT), virtual planning, prototyping, and computer-guided surgery systems.15–17 The aim of this study was to present the factors important for planning of immediate loading of implants through a literature review to provide enough information for treatment success. 504 Vol. XXXVIII /Special Issue No. One /2012
