简要总结
A randomized clinical trial (RCT) was designed. Fourteen completely edentulous participants were randomly allocated into two equal groups. All participants received two implants in the inter-foraminal area with ball attachments. Participants in the control group were rehabilitated with conventionally manufactured Polymethyl Methacrylate (PMMA) maxillary complete denture and mandibular implant overdentures while participants in intervention group received digital light processed (DLP)-printed photo-polymerizable PMMA Nextdent maxillary complete denture and mandibular implant overdentures. Follow-up appointments were scheduled at 3,6, and 12 months where data of Oral Health Impact Profile 19(OHIPEDENT19) was used to assess the OHRQoL (oral health related quality of life). In addition, denture retention was measured using digital force gauge device. Data were collected and statistically analyzed.

结局指标
主要结局
. OHRQoL (oral health related quality of life)
时间窗: 12 months
Oral Health Impact Profile 19 (OHIPEDENT19) was used to assess the OHRQoL (oral health related quality of life). The questionnaire was translated to Arabic and validated (S2).24 The profile consisted of 19 questions each with score 0 to 4 (impaired) on Likert scale; accordingly, for each patient the minimum score was 0 and maximum score was 76.
次要结局
- Overdentures' retention(12 months)
