Comparison of Post-operative Complications of Bone Augmentation at Anterior of Maxilla After Periosteal Releasing Incision With Two Techniques Diode Laser and Scalpel

September 10, 2016 updated by: Neda Moslemi, Tehran University of Medical Sciences
The aim of this study was to investigate if using lasers instead of scalpel for flap advancement in bone augmentation procedures would reduce post-operative swelling and pain.

Detailed Description

Guided bone regeneration (GBR) is a well established method to augment excessive alveolar bone loss before and at the time of implant placement. Primary closure of soft tissue is a prerequisite for successful bone augmentation procedures. Adequate flap advancement is a key factor for tension free primary wound closure. The tension free flap is usually attained by incising the buccal flap using scalpels. However, this procedure, especially in cases with major flap advancement, results in increased patient morbidity after surgery. Swelling and hemorrhage during the first week after surgery have a negative effect on patient's quality of life.

Currently, lasers are widely used as a tool for soft tissue management and diode laser appears to be an effective tool for incision and excision of the soft tissue. The major advantageous property of lasers is ablation of tissue together with effective hemostasis, minimal swelling and virtually no pain.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
post-operative swelling intensity
Time Frame: Within the first 6 days after surgery
Swelling on the operated side was evaluated as follows: 0 (none: no inflammation), 1 (mild: intraoral swelling confined to the surgical field), 2 (moderate: extra oral swelling in the surgical zone), or 3 (intense: extra oral swelling spreading beyond the surgical zone).
Within the first 6 days after surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
post-operative pain intensity
Time Frame: Within the first 6 days after surgery
Postoperative pain was measured using a visual analog scale (VAS) ranging from zero for "no pain" to 100 for "the worst possible pain".(questionnaire)
Within the first 6 days after surgery
implant success
Time Frame: 3 months later
based on Albrektsson success criteria.
