**NCT ID:** [NCT04648514](https://clinicaltrials.gov/study/NCT04648514)

## Key Facts

- **Status:** UNKNOWN
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 32
- **Lead Sponsor:** Cairo University
- **Conditions:** Evaluations, Diagnostic Self
- **Start Date:** 2020-10-01
- **Completion Date:** 2021-09-30
- **CT.gov Last Update:** 2020-12-01

## Brief Summary

Radiographic evaluation of bone height gain with dental implant placed simultaneously with closed sinus lifting using hydraulic lift technique versus summers' osteotome technique in posterior edentulous maxilla (RCT)

## Detailed Description

Evaluation will be done on the amount of bone height gain radiographically (using both panorama and CBCT) after placement of the dental implant simultaneously with closed sinus lifting using hydraulic lift technique versus summers' osteotome technique in patients with posterior edentulous maxilla (Randomized Clinical Trial)

## Eligibility

- **Minimum age:** 20 Years
- **Maximum age:** 80 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
Inclusion Criteria:

* Edentulous patients in the maxillary posterior region .
* Patients in need to fixed restorations in posterior region .
* Patients with a healthy systemic conditions.(Apparently medically free)
* Patients with adequate inter-arch space for placement of the prosthetic part of the implant .
* Patients who had approximately 5-8 mm of available bone height between crest of bone and floor of sinus
* Both sexes.
* Patients with Good oral hygiene
* Patients more than 20 years old
* Cooperative and motivated patients

Exclusion Criteria:

* Patients with local pathological defects related to posterior maxilla .
* Heavy smokers.
* Abnormal habits that may alter results such as alcoholism or parafuctional habits .
* Patients with systemic diseases that may affect normal healing.
* Patients with psychiatric problem
* Patients with history of recent radiation therapy to the head and neck area .
* Patients with aggressive periodontitis .
```

## Arms

- **Using of bone osteotomes for closed sinus lifting** (ACTIVE_COMPARATOR) — Using of summers' osteotome technique by bone osteotomes for closed sinus lifting then evaluation the amount of bone height gain will be done radiographically (by panorama and CBCT) after implant placement in posterior edentulous maxilla .
- **Patient satisfaction evaluation after using bone osteotomes** (ACTIVE_COMPARATOR) — Evaluation of patient satisfaction numerically will be done after using summers' osteotome technique by bone osteotomes for closed sinus lifting in posterior edentulous maxilla

## Interventions

- **Using of hydraulic lifter device for closed sinus lifting** (PROCEDURE) — Using of recent closed minimally invasive technique (hydraulic left technique) by hydraulic lifter device for closed sinus lifting then evaluation of the amount of bone height gain will be done radiographically (by panorama and CBCT) after implant placement for patients with posterior edentulous maxilla .
- **patient satisfaction evaluation after using hydraulic lifter device** (BEHAVIORAL) — Evaluation of patient satisfaction numerically will be done after using hydraulic lift technique by hydraulic lifter device for closed sinus lifting in posterior edentulous maxilla

## Primary Outcomes

- **Amount of bone height change** _(time frame: 6 months)_ — Evaluation of the amount of bone height change radiographically after closed sinus lift simultaneously with implant placement using hydraulic lift technique versus summers' osteotome technique in posterior edentulous maxilla

## Secondary Outcomes

- **Patient satisfaction numerical questionnaire** _(time frame: 6 months)_
