초록

The purpose of this study was to evaluate the Osstem implants (US II/SS II implants) through the retrospective study for the clinical success
rate during the installation of the Osstem implants (US II/SS II implants) by using of the procedures of maxillary sinus floor elevation.
Materials and methods: The current study was researched in the 6 medical institutions: Chonnam National University, Chosun University, Pusan
DaeDong Hospital, Bundang Seoul National University Hospital, Ap-Seon Clinic, and All Clinic. Based on the total number of 116 patients whose
treatment was the installation of the US II/SS II implants with the procedures of the maxillary sinus floor elevation, they were conferred on the dental
records of the patients under the joint consultation of the 6 medical institutions.
On the dental recording charts, there were included in as the following; the name of the institutions, gender, age, with or without smoking or drinking,
with or without the generalized diseases, the height of the alveolar bone on the operational sites, elapsed edentulous state period, the state of the
opposed or adjacent teeth, the methods of the maxillary sinus floor elevation, secondary time period for surgery, the lengths, types, and diameters of
implants, with or without bone transplantation or the types of bone, postoperative current bone height, current adjacent soft tissue state of the implants,
with or without the success of the installations of the implants. We have done our survey with the clinical and radiolographical examinations and dental
questionaries. The success and survival rate of the implants was evaluated.
Results
1. Total number of the patients with the installation of the US II implants were 62. The 252 numbers of US II implants were installed on the 89 maxillary
sinuses. The patient's mean age was 54.1 years old and there were 36 men and 27 women.
2. Total number of patients with the installation of SS II implant were 57. The 165 numbers of SS II implants were planted on the 80 maxillary
sinuses. Their mean age was 48.7 years old and there were 37 men and 20 women.
3. The follow-up period was 30.7 months(21-49 mon) on average. The vertical bone loss of installed implants after the procedures of the maxillary
sinus elevation was 1.1 mm on average in SS II and 1.3 mm on average in US II. There existed no statistical significance on each group. The
mean enlarged bone height after the maxillary sinus floor elevation was 8.2 mm.
4. For the procedures of the maxillary sinus elevation, the Lateral approach technique occupied 87.1%, which was the most used one. In addition,
the most frequently used transplanted bone was autogenous bone only which was 72.7% during the maxillary sinus floor elevation.
5. The complication of maxillary sinus floor elevation were perforation of sinus membrane, disesthesia on doner site, exposure of cover screw and
exposure of maxillar bone.
6. The survival rate of US II and SS II after maxillary sinus floor elevation was 99.2% and 95.8%, respectively. And the success rate of US II and
SS II after maxillary sinus floor elevation was 97.6% and 89.7%, respectively.
Conclusion : On the evaluation of the analysis of our study, both US II and SS II implants showed the excellent clinical results by use of the procedures
of maxillary sinus floor elevation.
