This procedure is instituted following periodontal therapy and continues at varying intervals, determined by the clinical evaluation of the dentist for the life of the dentition or any implant reolacements. It includes removal of the bacterial plaque and calculus from suragingival and subgingival regions, site specific scsaling and root planning where indicated, and polishing the teeth. If new or recusrring periodontal disease appears, additional diagnostic and treatment procesures must be considered.
Drug Induced Hyperplasia
A soft tissue flap is reflected or resected to allow debridement
of the root surface and the removal of granulation tissue. Osseous
recontouring is not accomplished in conjunction with this
procedure. May include open falp curettage,reverse bevel flap
surgery, modified Kirkland flap procedure, and modified Widman
surgery. This procedure is performed in the presence of moderate to
deep probing depths, loss of attachement, need to maintain
esthetics, need for increased access to the root surface and
alveolar bone, or to determine the presence of a cracked tooth,
fractures root, or external root resporption. Other procedures may
be required concurrent to D4240 and should be reported separately
using their own unique codes.
Bone Grafting Procedure
This procedure involves the use of grafts to stimulate periodointal regeneration when the disease process has led to a deformity of the bone. This procedure does not include flap entry and closure, wound debridemen, osseous contouring, or the placement of biologic materials to aid in osseous tissue regeneration or barrier membranes. Other seprate procedures delivered concurrently are documented with their own codes.
Tissue Graft Procedure
This procedure is perforned to create or augment gingiva, to obtain root coverage to elimate sensitivity and to prevent root caries, to elimate frenum pull, to extend the vestibular fornix, to augment collapsed ridges, to provide an adequate gingval interface with a restoration or to cover bone or ridge regeneration sites when adequate gingival tissues are not availble for effective closure. there are two surgical sites. the recipient site utilizes a split thickness incision, retaining the overlying flap of gingiva and/or mucosa. the connective tissue is dissected from the donor site leaving an epithelialized falp for closure. After the graft is places on the recipient site, it iis covered with the retained overlying flap.
Debridement of peri-implant defect or defects surrounding a single implant, and surface cleaning of the exposed implant surfaces, including flap entry and closure. Bone graft for repair of peri-implant -does not include flap entry and closure. Placement of a barrier membrane or biologic materials toaid in osseous regeneration are reported separately.
