It is appropriate to establish a balance between prosthetic and anatomical concerns when inserting an implant. If a clinician focuses on anatomical concerns, he or she may place the implant at an angle to avoid adjacent teeth or fenestrating the buccal or lingual bone plates. Then, to achieve prosthetically desired parallelism between implants or teeth, the clinician can place an angled abutment. Based on the limited clinical trials reported in the literature, angled abutments result in increased stress on the implants and adjacent bone, but within the physiological limit.
Numerous types of prefabricated abutments are available at specific angles. Preangled abutments with angulations varying from 15 to 35° often are commercially available. Furthermore, laboratory technicians can fabricate custom abutments to contours needed for a satisfactory prosthetic reconstruction wherein we have to select proper angulations.
