NCT06816277

Brief Summary

A randomized clinical trial was carried out in patients affected by peri-implantitis with a follow-up of 60 days. Melatonin 1.9 mg or placebo was applied locally to the peri-implant defect after nonsurgical debridement. To determine the effectiveness anti-inflammatory, osteogenic and antimicrobial properties were evaluated. The probing depth, bleeding index, plaque index, and interleukin-1β and 6 concentrations, peri-implant bone level and the bacterial strains were analyzed.

Outcome Measures

Primary Outcomes (1)

  • Probing depth

    The distance from the gingival margin to the bottom of the periodontal pocket was considered. The measurement was carried out in the four locations surrounding the implant, mesial, distal, lingual and vestibular. Additionally, the average of the four locations was presented.

EXPERIMENTAL

El tratamiento periimplantario y el desbridamiento mecánico se realizarán en todos los casos bajo anestesia local convencional. El procedimiento seguirá la secuencia habitual en todos los casos. El acceso quirúrgico se hará a través de una incisión intrasulcular y lineal, y el desprendimiento de un colgajo mucoperiostéico. El tratamiento peri-implante se realizará con una punta de ultrasonido bajo irrigación, complementada con el uso de curetas si es necesario. Posteriormente, en los casos del grupo correspondiente, se aplicará melatonina (1,9 mg) a la cama periimplantacional. Suturado con seda monofilamento 4/0 en una aguja semicircular de 3/8 premontada. Después de 7 días, se revisará el proceso de curación y se eliminarán las suturas.

Placebo

PLACEBO COMPARATOR

The peri-implant treatment and mechanical debridement will be performed in all cases under conventional local anesthesia. The procedure will follow the usual sequence in all cases. Surgical access will be made through an intrasulcular and linear incision, and the detachment of a mucoperiosteal flap. The peri-implant treatment will be performed with an ultrasound tip under irrigation, complemented by the use of curettes if necessary. Subsequently, in the cases of the corresponding group, melatonin (1.9 mg) will be applied to the peri-implant bed. sutured with 4/0 monofilament silk on a pre-mounted 3/8 semicircular needle. After 7 days, the healing process will be reviewed and the sutures will be removed.

Interventions

The implant with the most severe involvement was selected, although the treatment was performed on all implants, to prevent patients with more affected implants from having greater statistical relevance. The peri-implant surgical treatment was performed under local infiltrative anesthesia with 4% articaine with 1:100,000 adrenaline. Debridement was performed using ultrasound with irrigation, complemented using curettes. Treatment with melatonin or placebo was applied through computer block randomization. To achieve blinding, a different code was assigned to the group applying 1.9 mg of melatonin (A) and to the control group (B) applying placebo (dextrinomaltose 2 mg) powder and the samples and records were coded. It was sutured with 4/0 monofilament in a pre-assembled 3/8 s
