Implant Stability Changes Using Different Technique in Posterior Maxilla With Early Loading Protocol

60 implants were placed in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with normal bone height beneath the floor of the maxillary sinus. The patients were selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.

60 implants will be randomly and uniformly divided into two equal groups: Group 1: It was consisted of 20 inserted dental implants by Densah burs into healed posterior maxillary alveolar ridge with an early loading pattern.

Group 2: It was consisted of 20 inserted dental implants by Magnetic Mallet technique into healed posterior maxillary alveolar ridge with an early loading pattern.

Group 3: It was consisted of 20 inserted dental implants by Conventional Drilling technique into healed posterior maxillary alveolar ridge with an early loading pattern.

Inclusion criteria

  • Patient with missing one or more posterior maxillary teeth.
  • Patients in the age group between 18 and 60 years old.
  • 10 mm or more vertical bone height is present.
  • No gender preface in selection of the patients.
  • Good oral hygiene.
  • Non-smokers.
  • Patients willing to be present during the study follow up intervals.
  • Patients free from any systemic diseases.
  • 6 mm or more ridge width is present.
  • Crown height space of at least 8 mm.
  • Patients without any para-functional habits (bruxism and clenching).

Exclusion criteria

  • Patients with any pathological lesion or root tips at the planned surgical site.
  • Patients with systemic diseases that contra-indicate the surgical procedure or affect bone healing process such as uncontrolled diabetes mellitus, bleeding disorders, serious osseous disorders, and mental disorders.
  • Patient taking drugs that could affect bone healing process as in immunosuppressive drugs and bisphosphonates.
  • Alcoholism.
  • Untreated periodontal disease or bad oral hygiene.
  • Pregnancy.

Treatment and study plan

Densah burs

Procedure

20 inserted dental implants by Densah burs into healed posterior maxillary alveolar ridge with an early loading pattern.

Magnetic Mallet technique

Procedure

20 inserted dental implants by Magnetic Mallet technique into healed posterior maxillary alveolar ridge with an early loading pattern.

Conventional drilling technique

Procedure

20 inserted dental implants by Conventional Drilling technique into healed posterior maxillary alveolar ridge with an early loading pattern.

Primary outcomes

  1. Implant stability

    Time frame: 2 months

    Implant stability was assessed at the time of implant insertion, 1 month and 2 months after surgery. The analysis of resonance frequency analysis (RFA) was made using an Osstell Mentor apparatus. The smart peg was attached to the dental implant. The RFA value was measured 4 times in 4 directions (every 90°). The results were expressed as implant stability quotient (ISQ) and averaged for each implant. The ISQ scale ranges from 0 to 100. The values less than 60 indicate low implant stability, values from 60 to 69 indicate medium stability, while values from 70 to 79 indicate high stability.
