Brief summary

In patients that are going to receive a dental implant in the posterior mandible (distal from canine), does the subperiosteal anesthetic technique with Articaine 1:100.000 4 % Epinephrine compared to the loco-regional one, produces the same analgesia during surgery ?

Detailed description

Inter/Intra observer agreement will be made for administration of local subperiosteal, loco-regional anesthesia, operatory evaluation of pain and radiologic examination. One group will receive articaine 1:100.000, 4% epinephrine subperiosteal and the other 1:100.000 4% epinephrine loco-regional for dental implant installation in posterior mandible. The evaluation parameters will focus on intraoperatory pain, Intraoperatory anesthetic complications, anesthetic efficiency, correlation between distance from implant to inferior alveolar nerve, intraoperatory pain, post-operatory at 3 and 10 days and correlate changes, and survival rate of dental implants during and post osseointegration period.

Design outcomes

Primary

MeasureTime frameDescription
Anesthesia efficiencyDuring Surgery for Dental Implant installationEvaluate subperiosteal vs loco-regional anesthesia for implant installation in posterior mandible. It will be measured by the amount (mean) of anesthesia pre and intraoperatory

Secondary

MeasureTime frameDescription
Intraoperatory PainDuring Surgery for Implant Installation in posterior mandibleIt will be measured with a direct measure composed by pre and post operatory questionnaires with Visual Analog Scales (VAS) to patient and by two indirect measures, one to the clinician that performed the surgery and one by an external clinic psychologist, both by means of VAS score
Intraoperatory Anesthesia ComplicationsDuring Surgery for implant installation in posterior mandiblemeasure the amount of adverse effects of both types of procedure (subperiosteal vs loco-regional)
Time of SurgeryDuring Surgical ProcedureMeasure the amount of time needed to perform dental implant installation in posterior mandible in both groups (subperiosteal Vs loco-regional)
Distance To Inferior Alveolar Nerve (IAN)Post operative Panoramic radiographmeasure in a panoramic (orthopantomography) the distance from the implant apex to the most coronal part of the IAN and correlate to the anesthesia efficacy and operatory pain
Post-Operatory Outcome ChangesBaseline (T0) 3 Days (T1) 10 Days (T2)measure post-operatory magnitude changes in both groups (subperiosteal vs loco-regional anesthesia) from baseline to 10 Days. It will be measured in VAS the amount of pain experienced by the patient.
