Microsurgical Instruments and Magnification May Enhance Treatment Outcomes Of Laterally Moved, Coronally Advanced Flap in Miller Class III Isolated Recession Defects

The benefits of microsurgical approaches in periodontal therapy have been described. The main focus of this study is to determine if using microsurgical LMCAF technique would improve the outcomes of the therapy for the Miller Class III isolated recession-type defects.

Six months results of this study showed that LMCAF with microsurgical approach offered better complete and mean root coverage results over macrosurgical LMCAF technique. The superior effect of microsurgical approach on post-operative morbidity can make this technique more preferable for the patients who expected comfortable postoperative period.

This study supports that using the microsurgical aproach with LMCAF procedure significantly affects the clinical and patient-centered success of treating Miller Class III isolated typed defects.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: laterally moved coronally advanced flap microsurgical; For the test group (LMCAF-M), the surgical procedures were performed with the aid of a galilean loupe, under 2.5x magnification vision, microsurgical instruments and microsurgical suture material .	Procedure: laterally moved coronally advanced flap with microsurgical instruments and x2.5 loupe; The recipient area for the laterally moved flap was prepared. When the flap was moved in the distal-mesial direction another short horizontal incision was performed at the most apical extension of this vertical incision. Once the mucogingival line was reached, flap elevation was continued split-thickness. Flap elevation was terminated when it was possible to passively move the flap laterally above the exposed root. Flap was sutured.
Active Comparator: laterally moved coronally advanced flap macrosurgical; For the control group (LMCAF), LMCAF was performed with conventional instruments (detaylı) and materials (stur). Loupe magnification, microsurgical instruments and suture material were not used in the control group.
