Abstract: BACKGROUND: With the development of computer-aided design and computer-aided manufacturing technology, zirconia abutments with a titanium base are widely used in clinic due to its good application advantages, but there are still some problems and a lack of consensus design standards.
OBJECTIVE: To review the fabrication methods of Ti-base zirconia abutment, and the effect of abutment connection, emergence design, abutment angle, and bonding on mechanical properties of Ti-base zirconia abutment. 
METHODS: Relevant literature published from 2010 to 2023 was searched in CNKI and PubMed databases with the search terms “zirconia abutment, titanium base” in Chinese and English, respectively. The search time limit was extended for some cl
RESULTS AND CONCLUSION: It is recommended that clinicians try to select antirotational titanium bases or rotational titanium bases with a Morse taper connection. Implants should be placed in the correct axial angulation of not more than 15° or with an inclination to the palatal side when using angled zirconia abutments. When a ≥ 30° labial inclination is followed for implant placement, the bite force must be decreased effectively to reduce the risk of mechanical and biological complications of implants, abutments, and prostheses. Ti-base zirconia abutments with a higher gingival height should be selected, and its restorative angle should not exceed 40°. Multilink Hybrid Abutment could be the first choice for extraoral bonding of zirconia abutment to titanium bases.
