Clinical Evaluation of the Modified Laterally Stretched Technique (RT2) Gingival Recession vs Tunneling With CT Grafting

Cairo University (CU)

Status: Active, not recruiting

Conditions: Gingival Recession

Treatments: Procedure: Modified laterally stretched technique with a connective tissue graft.

Study type: Interventional

Funder types: Other

Identifiers

NCT06044870

About

Regression analysis in a recent systematic review showed significantly greater mRC and CRC values when modifications are done to the TUN procedure to achieve more coronal advancement of the flap, coronal advancement also helps in covering the underlying graft for better recession coverage outcomes (Tavelli et al., 2018), limited data is present on the possible influence of a covered or partially uncovered graft. However, it has been suggested that minimal exposure of the CTG may aid not only in achieving CRC but also a harmonious gingival margin (John et al., 2015; Rasperini et al., 2011).

Modified laterally stretched technique with a connective tissue graft.

Experimental group

Description:

After the administration of local anesthesia, root planing of the exposed root surfaces will be performed by means of hand instruments. A partial thickness envelope is performed with tunneling instruments involving one or two teeth adjacent to the tooth, in case of a very thin biotype a complete thickness envelope could be done. Two horizontal incisions are done at the base of the papillae of the deepest recession site, allowing to place the graft in a more coronal position and improving access and visibility.

Treatment:

Procedure: Modified laterally stretched technique with a connective tissue graft.

Tunneling technique with connective tissue graft.

Active Comparator group

Description:

Immediately before surgery, contact point composite stops were placed to prevent the collapse of the suspended sutures in the inter-proximal spaces.• The entire gingival papillary complex will be moved coronally using a suspended suture anchored in the lingual gingiva (Aroca et al., 2010, 2013; Azzi et al, 2002, zuhr et al.,2009).

Treatment:

Procedure: Modified laterally stretched technique with a connective tissue graft.
