AIM: the aim of the present study is to verify the early stage of peri-implant tissue healing, in patients exhibiting complete and partial edentulism treated with immediate loading of post-extractive monophasic and biphasic implants. The present study is based on the response of tissues and of the implant-bone interface, while comparing implants with different morphologies, both wide and narrow spiral implants according to the surgical technique.
METHODS: This study is based on the predictability of results achieved on a group of 21 patients, 11 males and 10 females aged between 34 and 78 years, whose medical history was taken before surgery and whose bone quality and quantity were assessed through instrumental investigations. Each patient was rehabilitated with a variable number of implants according to his/her needs, by means of wide or narrow spiral implants for a total of 60 implants placed in the upper jaw and 48 in the lower jaw in variable areas.
In 71% of cases, implants were immediately loaded on latero-posterior areas.
Healing of peri-implant tissues and osseointegration of each implant was monitored on each patient with a follow-up protocol at 15 days, 1 month, 3 months, 6 months and 1 year.
RESULTS: Long-term controls showed proper and sufficient osseointegration of immediately loaded implants both in patients exhibiting complete and partial edentulism, irrespective of the surgical technique and implant morphology. This was achieved following the protocols of implant bed preparation, primary retention, oral hygiene and follow-up. 96% of cases showed implant success, while 4% of cases failed because of a fracture to the provisional implant, due to splinting and welding defects.
CONCLUSION: In the light of the results achieved in the present study, the Authors observed that it is possible to proceed with immediate loading in any area of the jaws in patients exhibiting complete edentulism, partial edentulism or monoedentulism, regardless of the shape of the implant body. The principle of soldering the dental prostheses has to be followed in order to avoid those micro-movements which could lead to implant failure.
