New regenerative techniques in severe atrophy and advantages of navigation

The particular truncated-conical macrogeometric shape of the implants modifies the maxillary bone creating an osteocondensation increasing the stability of implants in this area. The navigation helps to find the best bone areas to use for an implant rehabilitation in the maxilla

Nowadays techniques for implant placement in the maxillary sinus area are well documented and have excellent clinical success. The minimum limit of bone height capable of stabilizing an implant in this region seems to be around 4mm; heights below this value impose a delayed positioning of the implant by proceeding first with surgery to lift the floor and the maxillary sinus and then with insertion of the implants 6-9 months later. Through this type of implant and this method it is possible to stabilize the implant up to bone heights close to 1 mm, giving a series of advantages which consist in reducing the total time for finalizing the case, solving the 3 necessary surgeries in a single time ( sinus lift, implant insertion, healing screw connection) to complete the case, consequently reducing the resulting therapeutic impact.

The characteristics of the implant are:

• Macromorphologically truncated-conical for a conometric coupling with the bone
• Lapped Titanium apex
• Progressive, expansive and dense thread from apex to platform with 0.4mm pitch
• Controlled progression in bone advancement
• Osseodensification by progressive expansion
• Rough surface until the platform
• Conometric Prosthetic Connection

The implant macrogeometry and the prosthetic connection represent one of the key points of the success of the maxillary sinus lift procedure with simultaneous stabilization of the implants in conditions of reduced bone height. Furthermore, the apical shape of the implant limits the impact of the insertion on the sinus membrane. The close-pitch thread significantly increases bone contact, facilitating control of implant progression in low bone height, limiting peak stresses and exerting controlled lateral osteocondensation.Through a conometric coupling procedure between the implant and the bone on which it is inserted, it is possible to stabilize it even in bone heights close to mm and through a conometric prosthetic connection it is possible to minimize marginal bone reabsorption in order to obtain a successful and reduce patient morbidity.

The conometric prosthetic connection is also able to obtain a better antibacterial seal compared to other connections to the full advantage of an absence of marginal bone loss.The insertion of the prosthesis “inside” the implant using a “SWITCHING PLATFORM” approach is able to reduce the biological insult on the gum caused by the continuous screwing and unscrewing of the prosthesis in the temporary stages of the work. The conometric connection seems to be an excellent solution also and especially in these cases of ADVANCED IMPLANTOLOGY as it manages to maintain and, in some cases, increase the bone around the implant for a better biological and aesthetic result.

Navigated surgery also allows you to find and use the most suitable areas of bone for implant placement and you can position implants of the most appropriate length and diameter in total safety. Surgery is much less invasive, the amount of anesthetic is reduced and patient acceptance is excellent. Cases with alternative solutions to maxillary sinus lift will be treated with the aid of Advanced Navigated Surgery
