I am going to do prosthetic treatment on #26, #27 2-month after CLP. Many dentists asked me when to carry out the prosthetic treatment procedures ( definite preparation ) after CLP, my answer is " TO ASK THE SURGEON ". The SURGEON is the only one who knows what he/she had done during CLP. "The quantity of ostectomy, osteoplasty" and "the thickness of soft tissue" and "the possibility of primary closure after suturing the wound" and " the remaining cementum on the exposed root surface after CLP", all will effect the time of healing about CLP. If a dentist can control all above mentioned situations, the healing time will be shortened and the would condition will be good and the waiting time for further prosthetic rehabilitation will be shortened too. So, the answer is depending on the surgeon.
