Abstract
Apparatus and methods for adjustably retaining a dental prosthesis are disclosed. In one variation, a securement assembly includes an abutment assembly comprising an upper abutment portion configured to extend beyond the gingiva of a patient. The upper abutment portion can have an abutment ledge and the abutment ledge can be defined by a receiving groove. The securement assembly can also include a coping attached to the abutment assembly. The coping can have a coping base. A seal can be positioned in the receiving groove and in between at least the abutment ledge and the coping base. The seal can elastically deform to allow the coping to translate relative to the abutment assembly.
Claims20
A securement assembly for retaining a dental prosthesis, comprising:
- an abutment assembly comprising an upper abutment portion configured to extend beyond the gingiva of a patient, wherein the upper abutment portion comprises an abutment ledge and the abutment ledge is defined by a receiving groove;
- a coping attached to the abutment assembly, wherein the coping comprises a coping base;
- and
- a seal positioned in the receiving groove and in between at least the abutment ledge and the coping base, wherein the seal is configured to elastically deform to allow the coping to translate relative to the abutment assembly while the coping is locked against the abutment assembly.
A securement assembly for retaining a dental prosthesis, comprising:
- an abutment assembly comprising an upper abutment portion configured to extend beyond the gingiva of a patient, wherein the upper abutment portion comprises an abutment ledge;
- a coping attached to the abutment assembly, wherein the coping has a coping base and an interior surface of the coping base is defined by a receiving groove;
- and
- a seal positioned in the receiving groove and in between at least the abutment ledge and the coping base, wherein the seal is configured to elastically deform to allow the coping to translate relative to the abutment assembly while the coping is locked against the abutment assembly.
A method of adjustably retaining an oral appliance in an oral cavity, comprising:
- securing an abutment assembly comprising an upper abutment portion in an oral cavity of a patient such that the upper abutment portion extends beyond the gingiva of the patient, wherein the upper abutment portion comprises an abutment ledge and the abutment ledge is defined by a receiving groove;
- positioning a seal in the receiving groove;
- coupling a sleeve comprising one or more locking flaps to the upper abutment portion;
- placing the oral appliance upon the upper abutment portion such that the seal is positioned in between the abutment ledge and a coping attached to the oral appliance, wherein the one or more locking flaps project radially outward to lock the oral appliance to the abutment assembly.
