Abstract: To assess the knowledge, attitude and practice among dental practitioners regarding management of short abutments receiving complete veneer crowns. A cross sectional survey was conducted with a pre-tested structured questionnaire containing 18 composite choice based questions among 250 practicing dentists on management of failed complete veneer crowns over short clinical abutments. Pertinent data were extracted and analyzed. 74% practitioners have agreed on modifying their tooth preparation after failure to enhance retention. 14.8% of the survey participants agreed on having performed crown lengthening for the same. 5.2% of the practitioners had performed orthodontic extrusion for the same. 20% reported to having relieved prematurities and 74% had stated to have relieved them out of occlusion. While 67% of them had tried post and core restorations to manage the same. Accomplishing retention in complete veneer crowns placed over short abutments has always posed a great challenge to the clinician. The knowledge and awareness level elicited in this questionnaire study is moderate. Hence more awareness programs and hands-on clinical training needs to be conducted to address this.
