This study aims to test the combined effects of different loading protocols and surgical approaches on clinical and patient-reported outcome measures (PROMs) following the use of four mini implants for mandibular overdenture retention. The main study hypotheses are: 1. There are significant improvements in PROMs following implant intervention compared to baseline measures; 2. Immediately loaded mini implants have similar failure rates compared to mini implants receiving a delayed 6-week protocol. 3. Flapless surgery has similar post-insertion outcomes compared to flapped surgery.

---|---|---|---|---|
Primary | Patient-perceived burdens | The Burdens in Oral Surgery Questionnaire (BiOS-Q) will be used to assess patient-perceived burdens. It includes 16 items concerning all aspects of procedures occurring during a surgery. Responses for each item are assessed using a visual analogue scale (VAS) ranging from 0 = no expression of the attribute (e.g. not unpleasant at all) to 100 = maximum expression (e.g. very unpleasant). | Twenty-four hours after implant surgery. | |
Primary | Implant survival and success | Each implant will be assessed according to the health scale of the International Congress of Oral Implantologists (ICOI-Pisa health scale). After clinical assessment, each implant will be classified as 'success', 'satisfactory survival', 'compromised survival' or 'failure'. | Incidence thoughout the 12-month follow-up after implant placement. | |
Primary | Postoperative pain and discomfort | A 100-cm graduated visual analog scale will be used to evaluate participants' assessments of pain and discomfort regarding the surgical process. Each participant will indicate their level of pain and discomfort with each parameter by marking a point along the scale. | Assessed 24 hours after implant placement. | |
Primary | Postoperative pain and discomfort | A 100-cm graduated visual analog scale will be used to evaluate participants' assessments of pain and discomfort regarding the surgical process. Each participant will indicate their level of pain and discomfort with each parameter by marking a point along the scale. | Assessed 72 hours after implant placement. | |
Primary | Postoperative pain and discomfort | A 100-cm graduated visual analog scale will be used to evaluate participants' assessments of pain and discomfort regarding the surgical process. Each participant will indicate their level of pain and discomfort with each parameter by marking a point along the scale. | Assessed 1 week after implant placement. | |
Primary | Consumption of analgesics | The number of analgesics consumed by the participant during the post-operative and healing period will be recorded in the patient's file. | Assessed until 1 week after implant placement. | |
Primary | Patient Satisfaction | The McGill Denture Satisfaction Instrument - DSI (Awad & Feine, 1998; de Grandmont et al., 1994) will be used to assess patients' satisfaction relating to their prostheses. This is a treatment-specific patient-based outcome assessing satisfaction relating to several aspects of the mandibular prosthesis, including general satisfaction, comfort, stability, aesthetics, chewing ability (ease of chewing), chewing efficiency (ability to crush food in small particles), ease of cleaning, ability to speak and oral condition (condition of their mouth, which can refer to oral health status and was measured by "In general, are you satisfied with your oral condition?''. The subjects will answer on a 100 mm visual analogue scale (VAS) anchored by the words 'not at all satisfied' and 'extremely satisfied'. | Assessed at baseline (before implant surgery) | |

Primary | Oral health-related quality of life (OHRQoL) | The cross-culturally adapted Brazilian version of the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT) will be used. It contains 19 items divided in four different subscale domains: (I) masticatory discomfort and disability (four items), (II) psychological discomfort and disability (five items), (III) social disability (five items), and (IV) oral pain and discomfort (five items). The items are answerable by a 3-point Likert scale and responses will be summed to result an overall score. Higher scores represent worse OHRQoL. | Assessed at baseline (before implant surgery). | |

Primary | Prosthodontic maintenance events | The incidence of prosthodontic repair/adjustment events will be recorded during the clinical assessments. | Throughout 12 months after overdenture delivery. | |
Primary | Surgical time | The time interval concerning the clinical visit for implant placement and delivery of the overdenture or denture adaptation will me measured and registered. | Procedure (Assessed during the clinical visit of implant placement and overdenture delivery or denture adaptation.) | |
Secondary | Masticatory Performance | To perform the masticatory performance test two gums in a dragée form will be used, one blue and one pink, which need to be stuck together manually by wetting them with water and applying moderate force. The participants will be instructed to chew 2 samples of the gum on theirs preferred chewing side for 20 and 50 chewing cycles, respectively, leaving an interval of 1 minute between each chewing sequence. | Assessed at baseline (before implant surgery). | |
