Early Loading of CDIC Implants for Anterior Tooth Restoration

Jiangang Chen, DDS, DMD, MSc/Chaorong Tie, DDS, MSc

Objective: Traditionally, the main prerequisites for osseointegration have been primary stability and the absence of loading for a period of 3-6 months. The recommended time between the placement and functional loading of a dental implant has been 4-6 months. But this waiting period may inconvenience patients because of the delay of final rehabilitation. Recent studies have shown that specially designed implants can result in increased bone-to-implant contact and early healing. This clinical study was evaluate the efficacy of early loading for anterior teeth using the CDIC (Chinese Dental Implant Center) implant. Methods: Seventy patients with missing anterior teeth were chosen. All received solid-screw or blade CDIC implants. In the test group Belle-glass or ceramometal prostheses were used for the implants after a maximum of 1 week. In the control group patients were given prostheses only after 6 months. Radiographic and clinical examinations were made postoperatively. Implant survival was recorded. Results: The survival rates were 95% and 96%, respectively, for early and late implants. Radiographic marginal bone resorption after 1 year, around all implants, was between 1.5 and 2 mm (P < 0.05). GI for all implants 1 year after loading were below 1. Conclusion: The present clinical trial indicated that, if primary stability of the implant is achieved, early loading is a promising treatment protocol for the future. The advantages of this procedure are obvious and include early function and esthetics. There is no need for a temporary denture. The total healing time and total treatment time are reduced. The CDIC system is suited to a 1-stage rapid-loading protocol for esthetic anterior tooth restoration.
