2-Week Loading Using ALX Implants and Prosthesis Supported by Cementless Link

Case Summary 🔎

Patient Information

  • Age/Sex: 73-year-old Female

  • Systemic Condition: History of osteoporosis, under medication (adjusted prior to implant surgery)


Clinical Findings

  • Tooth Site: #36, #37

  • Oral Examination: Tooth #36 presents with severe mobility associated with inflammation. Teeth #37 is missing.

  • Diagnosis: Apical Periodontitis on #36, Edentulous area #37


Clinical Summary

The patient presented with mobility and pain in the mandibular left first molar (#36), and radiographic evaluation revealed a periapical lesion suggestive of apical periodontitis. The patient also requested restoration of the adjacent edentulous area (#37). #36 was extracted, and an implant was immediately placed. Due to bone deficiency in the posterior mandible, guided bone regeneration (GBR) was performed. ALX implants provided excellent primary stability, enabling early loading. A final prosthesis was delivered two weeks postoperatively, supported by Cementless Link. At the 1-month follow-up, the prosthesis showed stable function with no complications.


Treatment Plan

  • Extraction of #36

  • Implant placement at #36, #37 with GBR

  • Digital impression taken on the day of surgery

  • Final restoration with Zirconia crown supported by Cementless link

  • 1 month follow up


Case Presentation

1️⃣ Pre-Op

  • #36 showed severe mobility, and a periapical radiolucency was observed on radiograph. #37 was missing and required prosthetic restoration.


2️⃣ Surgery - ALX Implant Placement

  • #36 was extracted and the surrounding inflammatory tissues was thoroughly debrided. 

  • Guided drilling was performed to ensure accuracy for immediate implant placement.

  • Due to the lack of crestal bone in immediate placement and the presence of dense D2 bone in the middle and apical areas (D022), Maxy tapping was performed.

  • Maxy tapping was performed following the depth markings, preparing the site for placement of a 5.5 × 6 mm implant.

  • An ALX-IT 5.5 × 6 mm, Cuff 3 mm was placed, 30N/cm was achieved.


  • Drilling was performed according to the axis of the #36 implant.

  • Due to the dense crestal bone, Maxy tapping was performed.

  • Well-defined threads can be seen in the prepared site following Maxy.

  • An ALX-IT 5.5 × 6 mm, Cuff 3 mm was placed, 30N/cm was achieved.

  • Implants for #36 and #37 were placed, and buccal dehiscence was observed.

  • Healing abutments were placed, and bone grafting was performed to address the buccal defect.

  • A collagen membrane was placed over the grafted area.

  • After suturing, a scan body healing abutment is connected for oral scanning. ISTV was measured at 76 (+6) for #36 and 82 (+4) for #37, adjusted according to the standard cuff height of 4 mm.

  • Digital impression captured using intraoral scanner.


3️⃣ Prosthetics

  • The prosthesis was fabricated using the Cementless Link (CL link).

  • The Cementless Link is an innovative prosthetic concept that achieves passive fit using only the Link and screw — without cement. The crown and Link are delivered intraorally as a single unit, enabling efficient and time-saving placement.

  • After two weeks, the soft tissue had healed, and sutures were removed.

  • The final prosthesis was delivered using the Cementless Link, allowing for easy and efficient connection without cement.

  • A final restoration was delivered.


4️⃣ Post-Op

5️⃣ Follow-Up

  • At the 1-month follow-up, the prosthesis remained stable, showing no complications.
