BASAL + CRESTAL IMPLANTOLOGY = STRATEGIC IMPLANTOLOGY
(Caution: this post may only make sense to my friends in the dental & medical fraternity)
Here is a case where we have employed both basal and crestal implant principles for implant placement in the maxilla and mandible to replace the missing premolars, facilitating immediate loading (fixation of teeth within 72 hrs of implant placement)
Maxilla – KOS Plus implant used to replace the rt. upper 2nd. pre-molar. The rough surface engages the cancellous bone (crestal bone engagement) while the smooth surface cortical flutes at the implant apex engages the cortical maxillary sinus floor (basal bone engagement). A heat cure acrylic temporary crown was placed within 72 hrs of implant placement which will be replaced with a Zirconia crown shortly.
Mandible – KOS – T implant used to replace the rt. lower 2nd. pre-molar. The long smooth surface neck engaging the soft tissue, the rough surface engaging the cancellous bone (crestal bone engagement) and the rough surface tip engaging the lingual cortical bone (basal bone engagement). This implant has been placed bye-passing the mandibular nerve as it exits from the mental foramen. A PFM crown was cemented within 72 hrs of implant placement.
Both these uniquely designed implants are from Ihde Dental, Switzerland.
This case is close to 2 years old. Imaging was done recently when he reported for a review appointment.
