Implant success today consists of more than just “osseointegration accomplished”. We also have to take into account the aesthetic result. The present clinical case with high aesthetic patient expectations illustrates the treatment of a partially edentulous 65-year-old female patient with grade 2 mobility in all teeth.
The Morse-tapered conical connection has been shown to be the most stable connection available at this time.
There is scientific evidence that micro-movements rather than the size of the microgap are the reason for bone loss. In a Morse-tapered conical connection, the internal line angle between the implant and the connector is less than 0.25 degrees. The microgap is smaller (1.1–1.5 μm) than a bacterium (2–6 μm) [2].
Therefore, this connection is the most stable connection currently known and associated with the lowest incidence of screw loosening (0.37 per cent).
DISCUSSION AND CONCLUSION
This case study uses an innovative implantological and prosthetic concept that allows the creation and stabilization of the peri-implant bone and gingival complex. Relevant scores were recorded for up to two years, yielding overall implant success rates near 100 per cent (99.7 per cent).
The aim of this research is to retrospectively evaluate an innovative implant and prosthetical design by applying the following criteria:
1. implant success rate,
2. bone loss and stability of bone level at the collar of the implant (The Morse tapered conical connection is proven to be the most stable connection at the present time. Therefore, some implant systems have already started to implement it, and they have proved the stability of the bone level using this connection (Bicon, Ankylos),
3. esthetics in terms of pink esthetic score,
4. thickness of the gingiva at 3 mm from the free gingival margin,
5. width of the keratinized gingiva around implants,
6. height of the gingiva around the implants
The study is comprised of the data of 137 patients with 608 implants (C-Tech, Bologna, Italy).
RESULTS: Only two implants were lost (after 6 months), both relating to a single patient. The success rate for those included in the 6-months, 12-months, 18-months and 24-months was 100 percent. Bone loss was not found in any participant of the study. The soft tissue scores indicated a highly esthetic result.
CONCLUSION: The implant system employed in the present study showed high success rates both for the stability in situ and for the esthetic aspects. Therefore, within the scope of the data collected it may be recommended for use in the population at large.
We present you a Surgical Clinical Case with Flapless Technique performed by Doctor Aldo De Blasi using SD Mini Implants. You will be able to observe all the steps necessary for the stabilization of the lower prosthesis in the interforaminal region.
Mini implants are a valid alternative to traditional implants, ideal for professionals looking for minimally invasive solutions for the stabilization of overdentures, for patients with limited space and bone volume and to reduce the costs of therapeutic treatments.
Dr. Aldo De Blasi:
He has graduated in Dentistry and Dental Prosthetics at “Università degli Studi di Milano”.
Particularly interested in professional development , in the last years he has followed elective courses to enhance his professional skills and knowledge, such as: Conservative dentistry and Endodontics, Periodontology, Implantology, Fixed Restorations on natural teeth and on dental implants.
He is now practicing his profession in Milan, where he especially deals with fixed prosthesis on natural teeth and implantology. He is also a nationally well-known lecturer, specialized in topics such as implant-prosthesis in elderly patients.
A 58 years old female patient has come to our clinic for lower jaw rehabilitation. After the clinical examination and OPG, We have decided to extract tooth 33, which is the only one remaining. As thepatient has not accepted a big augmentation procedure, we have decided to implant 4 C-Tech SD mini dental implants for retention and stabilization of the lower denture.
Clinical examination and 3D images has revealed the presence of a deep concavity in the residual alveolar ridge so we have decided to perform classic flap(open) technique. A mid crest incision and full muco-periosteal flap was raised. Alveoplasty is performed to achieve a better bone platform for the mini dental implants and to increase vertical dimension for the denture.
The osteotomy is preformed using a normal mini dental implant protocol with a 1.1mm bur.
The diameter of mini dental implants was 1.8x13mm. As we have achieved satisfactory primary stability of the implants, we have decided to immediately load them. An impression was taken with transfers and a final restoration is delivered 3 days later.
In summary one should keep in mind, that whenever there is any doubt about the ridge dimension, shape etc., whenever there are limitations with bone dimension, one should always perform an open flap technique because it is the only way that you can visualize the position of the implants!
SD mini dental implants are a very good and permanent solution when they are used in the right way!!
