Direct pick-up versus indirect pick-up technique for 4- implants retained single maxillary overdentures with bar attachment: Clinical evaluation.

Purpose of Statement : This study was conducted to assess the retention and soft tissue condition (gingival index, pocket depth (sound)) of retained implants in the maxilla using bar attachments that were placed using different pick-up techniques (direct and indirect techniques) were manufactured. materials and methods : Twenty patients with edentulous upper arches were divided into two groups according to their treatment modalities. The first group used the direct pick-up technique to place four implants in the canine and molar areas, and the second group used the indirect pick-up technique to place four implants in the canine and molar areas. Dental implants were assessed for retention using (force meter analysis) and pre-implant conditions (probing depth and gingival index) were assessed using silliness and low index. These assessments were established at loading, 1 month, 3 months, and 6 months later. Data were collected and the values of changes between each successive time were tabulated. Results: There is no statistically significant difference between the two groups observed throughout the study period for changes in retention values between the two groups after a one-month overdenture insertion. The probing depth showed no significant increase with time. though there was a statistically significant increase in probing depth in Group A (use of bar attachments with direct pick-up technique) than in Group B (use of bar attachments with indirect pick-up technique during prosthesis processing) after 1 month. Conclusion: Overall, bar-retained maxillary implants were associated with a high retention score and satisfactory peri-implant condition.
