BT ZYGOMAX
The perfect implant to resolve severe or very serious bone atrophies
The BT ZYGOMAX implant is used in cases of partial or total maxillary edentulism and therefore placed in a multi-implant system (for example all-on-4) in which the loads are distributed.
The BT ZYGOMAX implant is extrasinusal and does not require perforation of the sinus membrane. In the extrasinusal approach, the implant is positioned on the external side of the maxilla, trying not to tear the sinus membrane itself.
Before the surgery, it is suggested to do a pre-operative study with radiographic images, CT images and any stereolithographic model of the maxilla.
BT RHYNO
RESOLUTION OF SERIOUS JAW ATROPHIES WITH NASAL ANCHORAGE
In the case of partial or total maxillary edentulism, BT RHYNO implants can be used to exploit the maxillary bone surrounding the nose. The relative implant site begins in the alveolar bone (which must be at least 3mm) in the premolar area and ends in the bone between the maxillary sinus and the nasal cavity.
The implants must therefore be long enough to cross the sinus. The BT RHYNO implant is available in lengths 20, 22, 24 and 26 mm. It is also the surgeon’s choice whether or not to add a bone graft based. It is always mandatory to monitor that there are no signs of sinus infection before proceeding with the surgical procedure.
Before the operation, it is recommended to carry out a pre- operative study with radiographic images, CT images and any stereolithographic model of the maxilla. It should be noted that the nasal implant is usually placed in a multi-implant system (for example all on 4) in which the loads are distributed.
Pterigo
IMPLANT DESIGN
The posterior area of the maxillary tuberosity is closely connected at the bone level with the pterygoid process of the sphenoid and with the wall of pyramidal process of the palatine, thus representing an appropriate anatomical structure, characterized by dense bone, suitable to support dental implants.
The pterygoid implant is an endosseous fixture, of 15-18 mm in length, positioned in the region of the superior maxillary tuber; the greater length of the implant, if compared to a standard fixture, allows to reach the pterygoid fossa and therefore the homonymous sphenoid abutment on which the anchoring takes place of the apical part of the implant. The pterygoid implant is generally used together with the placement of other fixtures or teeth placed in the mesial area with respect to the maxillary sinus.
