Atrophy of Edentulous Alveolar Ridge Clinical Trial
Official title:
Evaluation of Dental Implant Placement in the Sloped Alveolar Ridge
The aim of this study was to investigate the therapeutic effect of sloped dental implants. It can reduce the need of osteoectomy, reduce discomfort of procedures, and is easier for maintenance.
20 OsseoSpeed ™ Profile EV and 20 OsseoSpeed ™ EV groups will be randomly implanted into the
oblique edentulous ridges of subjects, and the treatment response will be monitored for 3
years. The implantation area will be randomly divided into two groups, One group was treated
with OsseoSpeed ™ Profile EV (sloped group) and the other group was treated with OsseoSpeed ™
EV (control group). The same patient had the same implant as the same quadrant.
The patient will be followed up regularly for follow-up, followed by clinical attachment
level, probing depth, bleeding on probing, keratinized gingival width (Keratinized gingiva),
mobility (mobility) and other clinical indicators of the measurement, regular dental
radiography, gingival crevicular fluid (GCF) collection and bone integration measurement.
After six months of implantation, prosthesis will delivered and loaded functionally, and
regular follow-up will be arranged. In each time of follow-up, examination will be carried
out with regards to periodontal pocket depth, clinical attachment height, periodontal
bleeding index, keratinized gingival width, and other clinical indicators of the measurement,
at the end of the experiment, that is, after three years, and then a dental root film
irradiation, GCF collection and osseointegration measurement.
