BTI presents exclusive solutions for different problems in severely resorbed atrophic maxillae.
With these solutions we increase the predictability and reduce the surgical trauma.
Solutions with Tiny® Implants
For very narrow crest bones.
To treat severely resorbed Atropic Maxillae, the Tiny® Implants offers 2 solutions:
With the Expansion-Compaction technique we improve the aesthetics and the biomechanics, and we obtain enough anatomical substrate for the insertion of the implants.
Expansion is indicated in edentations with a residual bone height equal to or greater than 10mm and a thickness of 3 to 5mm. This technique consists of provoking a greenstick fracture of the crest bone with the vestibular displacement of the bone.
Due to the conical shape of the apex of these implants and the body diameters, so narrow, it is possible to insert them in severely resorbed alveolar processes where another type of implant would not be possible. In addition, their narrow platform is adequate to avoid bone retractions at a crestal level. All this means that surgery using these techniques is totally predictable.
It is a longitudinal corticotomy along the crest bone, both in the upper and lower maxillae. An ideal technique when the length of the vestibular bone to be displaced is big and a vertical release incision can be made, or not.
The incision is made in the middle of the crest bone, with the ultrasonic cutting device (BTI Ultrasonic), that offers excellent control over the cutting process.
Solutions with Short and Extra-Short Implants
For height problems.
Short and extra-short implants offer exclusive solutions for atrophic maxillae with vertical bone loss and as an alternative to more invasive surgical procedures.
This technique consists of the regeneration of the residual crest bone in height and around the inserted implants, using autologous bone obtained during the drilling and Endoret® (prgf®) to mix with this bone.
When placing the implant, it is done so in a supracrestal position, later covering it with autologous bone, Endoret® (prgf®) and a fibrin membrane.
A surgical technique that enables a bone augmentation, with the aim of obtaining an adequate bone floor on which to place the implants, after a loss in height.
1.- Summers Technique
It is a not too invasive technique that enables you to compact the bone and elevate the sinus floor provoking a greenstick fracture of the cortical bone
It consists of alternately introducing drills and osteotomes until the implant diameter is reached, to then insert the bone graft, elevate the sinus membrane and place the implant for its osseointegration.
Less invasive and as a clear variation of this technique, BTI has frontal cutting drills that facilitate drilling the sinus cortical bone after having achieved the diameter required for the implant. This cortical bone is worked on, eroding it until Schneider's membrane is reached; then, the graft material and the implant are inserted.
2.- Lateral Corticotomy Technique
It consists of creating a lateral access in the sinus by means of a window, through which the filling graft is inserted, after detaching Schneider's membrane. The sealing is carried out with a fibrin membrane and depending on the initial bone height, the implants can be inserted. Otherwise it will be necessary to wait 5 or 6 months, to reopen and place the implant.
