The most important etiologic factors of gingival recession are the presence of supraand sub-gingival calculus, inadequate width of keratinized tissue
, and faulty tooth brushing techniques.5
10,166,180 B2; Marty Richard Hunter of Surrey, CA has patented a method for treating a keratinized tissue
that entails conducting one or more treatment cycles.
However, coronally advanced flap (CAF) is a predictable surgical procedure when there is adequate keratinized tissue
present apical to the recession defect in the treatment of Miller Class I and II gingival recessions. CAF alone gives an unstable result for long-term period, despite of having many advantages.
In the region of2.1, a small band of keratinized tissue
(1 mm) was found apical to the gingival margin, and scars extending from the region of1.1 to 2.2 were found (Figure 1).
In the white circle numerous melanosomes can be noticed, spread in the keratinized tissue
The following clinical parameters were recorded by means of a periodontal probe at baseline and after six months: gingival recession depth (GRD0 and GRD6), gingival recession width (GRW0 and GRW6), and the width of the keratinized tissue
(KT0 and KT6).
The objective of the study is to evaluate whether there is a positive correlation between the gingival thickness, width of the zone of gingival keratinized tissue
and periodontal status.
A study was done to evaluate the safety of a tissue-engineered human ex vivo-produced oral mucosa equivalent (EVPOME) in intraoral grafting procedures and they have arrived at a result stating that this technique provides the ability to augment keratinized tissue
around teeth (18).
The presence of keratinized tissue
next to an oral implant presents greater benefits than with natural teeth since the keratinized gingiva has more hemidesmosomes and hence provides greater strength to the implant soft tissue interface; also, the submerged implant is less likely to become exposed during the healing process.
After a 90-day period of healing, a crestal incision was performed on the hemimandible designed to be submitted to conventional loading, maintaining similar quantities of keratinized tissue
on each side of the incision, and a mucoperiosteal flap was reflected.
There must be enough alveolar bone sup- port in all dimensions with sufficient attached keratinized tissue
to allow for stabilization of the transplanted tooth.
