The fixation of dental implant crowns is related to the gingival distance of the oral cavity, the gingival distance of the jaw is greater than five millimeters, and the screw fixation is chosen when the gingival distance of the jaw is lower.
1. Bonding cementation: clinically, according to the distance between the gingiva to choose the abutment height, bonding cementation requires the abutment height is greater than or equal to four millimeters, the abutment tip has more than one millimeter of restoration space, so the gingival distance is greater than five millimeters when you can choose bonding cementation.
2. Screw fixation: screw fixation is suitable for oral cavity with low gingival distance, low gingival distance bonding fixation does not have enough fixation force, and it can only rely on the mechanical force of screws for fixation.
The best way of fixation for dental implant crowns needs to be judged according to one’s own oral situation.
