Twenty patients (mean age ¼ 59.32 6 4.1 years) with moderately controlled diabetes mellitus (glycated hemoglobin A1c [HbA1c] ¼ 8.1%-10.0 %) were rehabilitated by maxillary and mandibular conventional dentures. Two small-diameter implants (3 3 12 mm) were inserted in the canine areas of the mandible and immediately loaded by mandibular dentures. In a split-mouth design, LLLI was applied to 1 of the 2 implants in a random order (study group [SG]); the other implant was left as a control (control group [CG]). For each patient, gallium aluminum-arsenide diode low-level laser (940-nm wavelength, 0.50 6 2 mW output power, 0.004 cm 2 spot size; Epic, Biolase, Inc, San Clemente, Calif) was applied around each implant with total delivered energy of 90 J (equally divided by 6 irradiation points) in 3 sessions. The application was done immediately after implant insertion, 3 days and 1 week after surgery. Implant stability (measured by Periotest) and marginal bone loss (MBL; measured by cone beam computerized tomography) were evaluated at implant loading (T1), 6 months (T6), and 12 months (T12). One implant failed in the CG and no failures occurred in the SG, resulting in 95% and 100% survival rates, respectively. The SG recorded higher Periotest values than the CG at all observation times. However, the difference was significant (P ¼ .039) at T6 only. The SG recorded lower MBL values than the CG. No difference in MBL was detected between groups or peri-implant sites (mesial, distal, buccal, and lingual) at T6 and T12. Within the limits of this study, LLLI had no effect on marginal bone around immediately loaded small-diameter implants retaining overdentures in patients with moderately controlled diabetes. However, it was beneficial in improving implant stability 6 months after overdenture insertion.

Twenty patients (mean age =59.32±4.1 years) with moderately controlled diabetes mellitus (HbA1c 8.1–10.0 %) were rehabilitated by maxillary and mandibular conventional dentures. Two small- diameter implants (3×12mm) were inserted in the canine areas of the mandible and immediately loaded by mandibular dentures. In a split mouth design, LLLI was applied to one of the two implants in a random order (study group, SG) and the other implant was left as a control (control group, CG). For each patient, Gallium aluminum-arsenide (GaAlAs) diode low-level laser (940 nm wavelength, 0.50±2 mW output power, .004 cm2 spot size, Epic Tm, Biolase®, Inc, San Clemente, California, USA) was applied around each implant with total delivered energy of 90 J (equally divided by 6 irradiat...

Vertical loads were applied simulating the masticatory forces unilaterally in the resected site and bilaterally in the central fossa of the lower first molar as 100N (tension and compression). Analysis was based on the assumption full osseointegration between different types of bones, and between implants and fibula while fixing the top surface of the TMJ in place.RESULTS: The metallic bar connecting the three implants is insensitive to the clips material.
