Abstract: Treatment of completely edentulous patients with implant over dentures became a common treatment modality that greatly improves the patient's quality of life. AIM: The aim of this randomized clinical trial was to evaluate three different types of implants retained over denture attachment for three years of fellow up. Material and Methods: In a randomized prospective trial 24 completely edentulous patients of age ranged from 50-65 years were carefully selected. The patients were divided into 3 groups group A patients of implant retained over denture with telescopic attachment, Group B patients of implant retained over denture with locator attachment and Group C implant retained over denture with ball and socket attachment, over three years radiographic evaluation was carried out

According to Zarb el al., 15acrylic denture was constructed first Then a radiographic template was prepared16. Two separate CBCT (dual scan technique) images of the radiographic stent were acquired using a CAT FLX V17, Nc 28273, Kavo, Charlotte, USA. data acquired from DICOM Superimposition in implant planning software (In2guide by 3DIEMME) ® allowed for precise evaluation of implant sites in edentulous regions (virtual placement of implants considering the relation to anatomical structures and prosthetic requirements) since the prosthesis could be seen over the accessible bone architecture. , Two implants positioned vertically (Narrow sky 3512, bredent, Germany) for all patients Two healing abutments were screwed into place after the canine regions were bilaterally implanted with narrow plate forms measuring 3.5 mm in diameter and 12 mm in length. The denture was put back into place with silicon soft lining materials after 7 days of healing, and it was meant to be worn for one month. Patients who got telescopic attachments for their implant-retained overdentures were randomly assigned to one of three groups of eight patients each based on GA. (GB): the individual who got an implant-retained overdenture that has a locator attachment (Gc): the individual who got an implant-retained overdenture that has a ball and socket fixation

Inclusion CritThe inclusion criteria of the study:

1. Patients who have no teeth have been at least six months since their last extraction
2. Having no underlying health conditions that could slow or prevent the repair of soft or hard tissues
3. Cone-beam computed tomography (CBCT) confirms that each patient has an adequate amount and quality of remaining alveolar bone,
4. Patients should have generally good dental hygiene
5. They should have an Angel class I maxillomandibular relation with at least 20 mm of inter-arch space for telescopic attachment, and 6. mm of residual alveolar bone width in the mandibular canine sections.

Exclusion Criteria:

• The exclusion criteria of the study:

  1. A patient who has already undergone radiation treatment to the neck and head area.
  2. With the present steroid treatment
  3. If they have a mental or neurological disability that could make it difficult for them to practice proper dentist care.
  4. When a person's immune system is weak.
  5. I have developed parafunctional behaviors.
  6. In cases where the patient is highly sedentary, frequently smokes, or otherwise refuses to cooperate with treatment.

Using a permuted block randomization procedure, patients were selected at random. By utilizing sealed envelopes, the individual responsible for assigning participants to the intervention arm remained oblivious to the allocation sequence and code. Somebody other than the people who took part in the study made this choice.
