Introduction: The aim of this study was to assess the reduced length implants as an alternative of conventional length implants in combination with bone augmentation. The following criteria were observed: survival rate, marginal bone loss, bleeding on probing.
Material and Methods: This study included 186 Straumann Standard Plus implants with dimensions: length of 6 mm and diameter of 4.8 mm. The implants were loaded with non-removable crowns or bridges at least 10 weeks after the implant placement. Depending on the type of the prosthetic option the distribution of the implants was as follows: 83 implants were co-abutments to one more implant with conventional length (8-14 mm); 67 implants were co-abutments to more than one implant with conventional length, 33 implants were loaded with single crowns.
Results: The mean period of observation was 5.59 years. The mean marginal bone resorption was 0,224mm. In 12.4% from the cases was registered BOP (bleeding on probing). A correlation was found between the BOP and mean marginal bone resorption. No correlation was found between the values of marginal bone resorption and the type of the prosthetics. The survival rate of the implants in the observation period was 99.5%.
Conclusion: Тreatment by short implants is a reliable alternative to implants with conventional length with combination of bone grafting procedures. It is less invasive, cost effective and consumes less treatment time.
