We prefer to use larger implants for the teeth in back (molars) as they take more stress, but some patients just don't have enough bone 'width' to accommodate these wide-body implants, so occasionally we will use two narrow diameter implants to support one molar. This approach saves the patient expensive bone grafting and quite a bit of time. We will explain the advantages of both and offer either approach to our patients for consideration during their consultation.
The XR below shows one finished tooth on the right ...crown is cemented on the implant. And the implant on the left has just been placed. In this case, an impression is made and the final crown will be cemented in two weeks. A soft comfort cap was placed on the abutment for those 2 weeks. You can see the implant "body" which is that part in the bone and the abutment which is above the gum line. The crown is cemented to the abutment. There are hundreds of manufactures making implants of different designs, shapes, materials....the choice is endless. We prefer a simple one-piece design, whenever possible as it saves the Patient and Doctor, both money and time. Two things we always seem to be running out of....:)
