SUMMARY
Aims: To study pain and swelling in the first week after dental
implant placement.
Material and methods: A total of 131 implants were placed in
41 patients (17 males and 24 females) under local anesthesia.
Pain was scored by means of a verbal and visual analog scale
(VAS), while swelling was evaluated by a verbal scale.
Results: Most patients who experienced pain reported the latter
to be slight, with a peak intensity 6 hours after the operation in
41.5% of cases. A significant relation was observed between pain
and the number of implants placed. Swelling was moderate in
most patients who reported pain peak intensity of inflamm ation
being recorded after 48 hours in 48.8% of cases. A significant
association was observed between swelling and older patients,
the placement of more than four dental implants, and operations
in which sinus lift or bone regeneration procedures were carried
out. Swelling was greater in patients with implants positioned
in the posterior sector versus those placed in the anterior zone,
and in those located at free extremes versus those placed in
interdental spaces or totally edentulous patients.
Conclusions: Following implant placement, pain tends to be
mild, with moderate inflammation. The latter is seen to be greater
in older patients, in subjects receiving a larger number of implants,
and in interventions involving regenerative techniques.
Key words: Pain, inflammation and dental implants.
INTRODUCTION
Following dental implant placement, patients present different
degrees of pain and swelling as a direct consequence of surgery
(1,2). A review of the literature has yielded few studies of pain
and inflammation following these procedures (1-3).
The present study examines postoperative pain and swelling in
patients subjected to dental implant placement, and their correlation
to different clinical and surgical parameters.
