Study summary

After teeth extraction and over years of removable denture wearing, atrophy of residual alveolar ridges progresses. The lower complete denture is the most problem issue in oral cavity due to bone loss and presence of the tongue, which is the most movable part in the oral cavity, this condition resulting in a lack of retention, stability, and support of the dentures, which directly affect the patient's confidence, function, comfort and bring a major challenge for prosthodontics

Inclusion criteria

. All patients should be free from any systemic diseases that might affect the bone quality or post-operative healing.

  • Completely edentulous patients with their age range from 55 to 65 years
  • All patients have Angle's Class I maxillomandibular relationship
  • Normal facial symmetry with no signs and symptoms of temporomandibular disorders.
  • Cooperative patients
  • Adequate inter-arch space.
  • All patients have recent and old extractions ,a period of at least 6 months from the date of last extraction.
  • All patients have lower arch with irregular buccolingual thickness .
  • Edentulous ridge covered by healthy firm mucoperiosteum, without abnormal morphology.
  • Normal tongue size.
  • All the selected patients should be free from any oral pathological lesions such as cysts, remaining root, or residual infection.

Exclusion criteria

Exclusion Criteria:

General health conditions preclude a minor surgical intervention, risk patients are excluded.

  • Local anesthesia with a vasoconstrictor is
  • therapy, prolonged intake of antibiotics or , or brittle metabolic disease history.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

    12 edentulous patients have mandibular ridges and have Angle's Class I maxillomandibular relationship

    Other: Implant

Interventions

  • OtherImplant

    Two (regular and narrow) dental implants will be placed in the canine region of the edentulous mandible according to surgical protocols, its 7 accurate position will be determined as relates to the vital structures by the cone beam radiograph.

What researchers measure

Primary outcomes

  1. Radiographical evaluation

    measuring the crestal bone height around implant by cone beam computed tomography (CBCT).

    Time frame: 3 months

  2. Radiographically

    measuring the crestal bone density around implant by cone beam computed tomography (CBCT).

    Time frame: 3 months
