1.Features of telescopic crown attachment (double crown):

A. A telescopic crown uses a dual crown structure to connect the denture to the abutment. The outer crown is integrally connected to the rest of the denture. The friction between the inner and outer crowns creates retention, ensuring optimal retention.
B. Telescopic dentures offer unique advantages: like all other precision attachments, they combine the self-removal and easy-cleaning benefits of removable dentures with the excellent functional recovery and minimal foreign body sensation of fixed dentures. They are particularly suitable for denture restoration after periodontal disease treatment, effectively acting as a periodontal splint.

2.Snap-on precision attachment features

Unilateral or bilateral free-standing tooth loss, partial loss of two or more teeth, prosthesis after mandibular resection, and overdenture restoration with multiple residual roots.

3. Tai Chi buckle precision accessory features

They are usually placed in the mesial or distal part of the abutment, and some can also be placed on the root surface of the abutment or on the implant abutment.

4. Characteristics of bolt-on precision accessories

A. Reduces operator difficulty, minimizes the number of clasps while ensuring good retention of the removable base, and allows for interchangeable accessories.
B. Unilateral or bilateral free-end defects, particularly suitable for cases with a small buccal-lingual diameter or vertical distance and a long free-end distance.
