Biologic width and crown lengthening
: case reports and review".
surgery: A restorative driven periodontal procedure.
Five weeks following nonsurgical endodontic therapy of tooth #3, the patient presented for crown lengthening
of teeth #2-5 under moderate sedation.
Specific techniques discussed include: tooth extraction, crown lengthening
, ridge expansion, maxillary sinus lift, bone grafting, and more.
In addition, tooth wear from erosion may reduce the crown height which in turn reduces the resistance and retention form which may warrant surgical crown lengthening
to overcome this.
They describe how to use these questions to determine a diagnosis and provide chapters on crown lengthening
surgery, tissue grafting, dentoalveolar intrusion of the adult dentition, forced eruption, orthognathic surgery, dental facial plastics, dentoalveolar extrusion, and sequencing the treatment plan, as well as providing a treatment-planning template on the accompanying CD and five case studies.
procedure was carried out using soft tissue laser in department of periodontology Rajarajeswari Dental College Bangalore.
In this case the traumatized central incisor had an extensive tooth structure loss which needed root canal treatment and crown lengthening
procedure to expose root margins to enable the operator to restore it with cast post and core where the aesthetic outcome of crown lengthening
procedure will be less than sat- isfactory due to the disruption of the gingival margin level in comparison with the adjacent teeth.
: The advantage of lasers in crown lengthening
is that it cuts only at the tip and they can be held parallel to long axis of the tooth to remove bone immediately adjacent to cementum without damaging it.
