The present article describes a treatment planning clinical strategy based on a flowchart developed to facilitate the treatment of teeth with severely compromised clinical crowns. The study comprised a group of 978 patients presenting with 2327 teeth needing clinical crown reconstruction. The patients were screened, diagnosed, and treated with a multidisciplinary approach according to a flowchart structure. A subgroup of 75 teeth in 62 patients was considered irrational to treat when a composite risk-evaluation model was applied. Another subgroup of 168 teeth in 126 patients required periodontal surgery and received a minimally invasive crown lengthening (MICL) procedure. Endodontic treatment was necessary for 73 teeth, and retreatment for 51. Most of the teeth (124 in 94 patients) received a full crown, while the remaining 44 teeth received a direct (24 teeth) or an indirect (20 teeth) reconstruction. Six teeth were orthodontically extruded before surgery. The 1-year average probing depth and clinical attachment level at the treated teeth was 2.5 ± 0.5 mm and 2.7 ± 0.6 mm, respectively. Bleeding on probing was detected in 19 sites (11.3%). No side effects or short-term recurrences were detected in 168 treated sites. Patients described function and esthetics as extremely satisfactory, very satisfactory, or satisfactory. In conclusion, an accurate screening based on a flowchart supported the clinical decision to treat 168 teeth with MICL and to replace 75 out of 2327 teeth presented at our clinic for restorations. The use of MICL and the high-quality restorations resulted in a healthy periodontal and dental condition of all the treated teeth as well as patient satisfaction at the 1-year follow-up.
