Early Loading of ALX-BT Implants in Different Bone Densities

Patient Information

• 64years, Female

• Medical History: Healthy

• Diagnosis: #36, #37 healed edentulous site (Extraction- March 2026)

• Treatment plan:

• -#36, #37 ALX-BT implant placement

• -Undersize drilling protocol

• -Early loading of Splinted full Zirconia  crown implant

  
  

Case Summary 🔎

A 64-year-old healthy female presented with healed edentulous sites at #36 and #37 following extraction in March 2026. ALX-BT implants (Ø4.5 neck / Ø5.0 body × 10 mm) were placed using an undersize drilling protocol. The bone densities were classified as D333 at #36 and D223 at #37. Despite the differences in bone density, adequate implant stability was achieved, allowing early loading with a splinted full-zirconia crown 3 weeks after implant placement. 

Case Presentation

1️⃣Pre-op 

• #36, #37 healed edentulous site, after teeth extraction 3months with under gingival contour & limited keratinized tissue zone.

2️⃣Surgery

• #46 healed edentulous site, with mild concavity & limited keratinized tissue of buccal gingival tissue.

• After full flap operation

• #36, #37 ALX-BT implant placement with D(neck)4.5/ D(body)5.0/ L10mm

• CMI Bone densities & Drilling bur steps:        

    - #36 (D333): D2.2-D3.0-D3.5 with L11.5mm                                      

    - #37 (D223): D2.2-D3.0-D3.5 with L11.5mm & D4.2/L10mm (final drill)

• Packing moldable Xenograft into the socket defect and performing buccal contour augmentation.

• #36 ALX-BT implant + Healing abutment D5.5mm/ GH6mm  IST = 75(+4)

  

• #37 ALX-BT implant + Healing abutment D5.5mm/ GH5mm  IST = 80(+2)

  

3️⃣Prosthesis 

• After #36, #37 implant placement 2weeks, IST remeasurement. #36 IST value = 77(+4) & #37 IST value = 83(+2). Connecting #36, #37 ALX-BT implant with scan body, digital impression for making Splinted full Zirconia crown implants.     

• CAD-CAM fabrication of Splinted full-Zirconia crown (#36, #37implants).

  

• After #36, #37 implant placement 3weeks, IST remeasurement. #36 IST value = 73(+4) & #37 IST value = 83(+2).  

  
  

  

• Final prosthetic delivery.

  

  
  

4️⃣Follow up

• 3-week follow-up after final restoration delivery.

Before & After Summary🔎

• #36, #37 ALX, D(neck)4.5/ D(body)5/ L10mm,    implant placement for new molar teeth replacement 

• #36 Bone densities D333 & #37 Bone densities D223.

• Early loading of the final splinted full Zirconia crown on implant #36, #37, 3weeks after implant placement.
