Study Notes

Periodontal surgery is used to improve periodontal instrumentation, reduce pocket depths, and regenerate lost periodontium.
It can also be used to improve the appearance of the periodontium and enhance prosthetic dental care.
Common relative contraindications for periodontal surgery include uncontrolled hypertension, recent heart attack, uncontrolled diabetes, and certain bleeding disorders.
Healing can occur through repair, reattachment, new attachment, or regeneration.
Healing by primary intention occurs when wound margins are closely adapted, while healing by secondary intention is slower.
A periodontal flap is a surgical procedure that allows for separation of surface tissues from tooth roots and alveolar bone.
Types of incisions utilized during periodontal flaps include crevicular and internal bevel incisions, as well as vertical releasing incisions.
Periodontal osseous resective surgery involves removal or reshaping of tooth-supporting bone.
An apically positioned flap can minimize periodontal pocket depths in patients with osseous craters caused by moderate periodontitis.
The modified Widman flap and laterally positioned flap are specific types of access flap procedures.
Gingival recession can be treated with laterally positioned autografts or coronally positioned flaps.
The lateral displaced pedicle flap involves a displaced flap that covers a neighboring recession defect.
The coronally positioned flap involves placing the flap margin above the original location.
Periodontal regeneration involves regenerating lost periodontal attachment apparatus.
Bone grafts can encourage regeneration of lost tissue.
Autografts, allografts, xenografts, and alloplasts can be used for bone replacement grafts.
Grafted sites should be left undisturbed for months and not probed until an appropriate interval has elapsed.
The dental hygienist should consult with the dentist to determine when a grafted site may be probed safely.
Periodontal regeneration is used in infrabony osseous defects and class Il furcation defects.
Guided tissue regeneration and barrier membranes can also be used in periodontal regeneration.
