TADs | Limestone Hills Orthodontics

What Are TADs?

TADs (Temporary Anchorage Devices, also called orthodontic miniscrews, mini-implants, or micro-implants) are small titanium screws threaded directly into the alveolar or palatal bone to create a stable anchor point for tooth movement. They are removed once treatment is complete and the bone fills the small channel within weeks.

The screw itself is roughly the diameter of a toothpick and 6 to 10 millimeters long.

TADs solve one of the oldest challenges in orthodontics: moving one tooth without moving the teeth next to it. Before TADs, the only way to anchor an orthodontic force was against other teeth, which meant the anchor teeth would drift in the opposite direction.

This effect, called reactive movement, undermines the treatment plan and limits how aggressively certain movements (intrusion, distalization, single-tooth asymmetric correction) can be attempted. TADs eliminate reactive movement because they are anchored in bone, not in adjacent teeth.

Whatever force the wire or elastic applies, the screw holds fast.

Why TADs Are a Precision Tool

Dr. Viecilli’s PhD research at Indiana University included finite element analysis of orthodontic force systems, the same biomechanical framework that produced the SmartArch™ wire patent.

Applied to TADs, that training calculates the exact vector, magnitude, and duration of force needed to move a specific tooth in a specific direction without root resorption, bone loss, or TAD failure. Most orthodontists place TADs by rule-of-thumb protocols. Limestone Hills places them by biomechanics.

When TADs Are the Right Tool

TADs are not used in every case. They are the right tool when the required tooth movement cannot be achieved predictably with braces or aligners alone, or when conventional anchorage would produce unwanted reactive movement. The most common indications at Limestone Hills:

Molar Intrusion (Open Bite)

Pushing back teeth up into the bone to close an anterior open bite. Without TADs, this movement typically requires orthognathic surgery. With TADs, intrusion mechanics often produce the same correction non-surgically.

Open-bite Treatment

MARPE (Adult Palatal Expansion)

Miniscrew-Assisted Rapid Palatal Expansion uses TADs placed in the palatal bone to deliver expansion force directly to the midpalatal suture in adults whose sutures have begun fusing. Without TADs, adult expansion usually requires SARPE surgery.

Palatal Expander

Impacted Canine Traction

Buried canines often need a heavy traction force over 6 to 18 months to bring the tooth into the arch. TADs provide a stable anchor that does not damage the roots of neighboring teeth the way conventional anchorage can.

Impacted Canine Treatment

Asymmetric Space Closure

Closing a gap on one side of the arch without dragging the teeth on the other side toward the gap. A TAD on the closing side eliminates unwanted reactive movement.

Distalization (Severe Crowding)

Pushing back teeth further back to create arch length for crowded front teeth without extracting premolars. TADs anchor the distalizing force directly to bone instead of pulling against the front teeth.

Gummy Smile Correction

Intruding upper front teeth to reduce excessive gingival display. Predictable intrusion requires skeletal anchorage from TADs or a surgical approach; conventional braces alone cannot deliver enough intrusive force without tipping the anchor teeth.

How TAD Placement Works at Limestone Hills Orthodontics

1 Free 3D CBCT Evaluation

Every new patient receives a complimentary i-CAT FLX CBCT scan at the consultation. The scan measures bone thickness, identifies tooth-root positions, locates nerves and sinus boundaries, and lets Dr. Viecilli plan the exact TAD position before any appliance is placed.

2 In-Office Placement (Same Day if Scheduled)

Placement takes roughly 10 minutes per screw. Dr. Viecilli uses a small amount of local anesthetic to numb the soft tissue, similar to a filling appointment. Patients describe the placement as mild pressure rather than pain. There is no drilling of tooth structure and no surgical flap. The screw is threaded directly through the tissue into the underlying bone.

3 Immediate Loading

Unlike dental implants, which require three to six months of osseointegration before they can hold force, TADs are designed for immediate loading. The orthodontic spring, elastic chain, or wire is attached the same day or within a week, and tooth movement starts.

4 Monitoring

Dr. Viecilli evaluates each TAD at every check-in for stability, tissue health, and movement progress. Loosening or migration is rare with bone-driven placement, but if it occurs, the TAD is replaced in-office the same day. Most TADs remain in place 4 to 8 months, depending on the planned tooth movement.

5 Removal

Once the planned movement is complete, the TAD is removed in-office in under 5 minutes, often without anesthetic because the screw is no longer integrated into bone. The soft tissue heals in a few days and leaves no visible scar. The bone remodels to fill the small channel within several weeks.

Why In-Office TAD Placement Matters

Most Austin-area orthodontists refer TAD placement to an oral surgeon. That referral pathway adds a separate consultation, a separate appointment, a separate copay, and typically two to six weeks of scheduling delay between the orthodontic plan and the start of TAD-supported tooth movement. Limestone Hills places TADs in the office, often the same day they are planned.

One Office, One Appointment, No Referral Delays

Dr. Viecilli places the TAD at the same visit where the appliance is adjusted. No outside surgeon, no second consultation, no waiting two to six weeks for the surgical office to schedule.

The Same Doctor Who Designed the Mechanics Places the TAD

Oral surgeons place implants reliably, but they do not design the orthodontic force system. When the orthodontic designer and the surgical planner are different people, position errors happen at the millimeter level that the force calculation does not tolerate. Dr. Viecilli designs the biomechanics and places the TAD; the position is optimized for the force that will act on it.

Included When Clinically Indicated

When TADs are part of a comprehensive orthodontic treatment plan at Limestone Hills, they are included at no additional charge: no surgeon fee, no separate TAD fee, no anchorage supplement. Standalone TADs for non-comprehensive cases are priced separately and explained at the consultation before placement.

Bone-Driven Placement, Not Rule-of-Thumb

The CBCT scan locates the safe bone window in three dimensions. The placement is planned around root positions, sinus floor, and nerve canal coordinates specific to the patient. No standard-protocol templates applied across cases.

What Does It Feel Like?

The most common patient question before placement is what the TAD will feel like. Three honest data points from Dr. Viecilli’s clinical experience at Limestone Hills:

During Placement

Local anesthetic numbs the soft tissue first. Patients feel pressure as the screw threads into the bone, similar to the pressure of a filling. Not sharp pain. The procedure takes 10 minutes per screw, and most of that is preparation; the actual placement is under one minute.

First 24 to 48 Hours

Mild soreness in the surrounding tissue, similar to the day after a heavy braces tightening. Acetaminophen or ibuprofen handles the discomfort. Soft foods on the first day; normal eating returns within 48 hours.

Throughout the Treatment Phase

Most patients forget the TAD is there. The screw head is small enough to sit flush with the gum tissue. There is no constant awareness of the appliance, the way patients feel a new bracket or a new aligner.

When to Call

Persistent pain beyond 72 hours, swelling that grows instead of shrinking, or a TAD that feels loose are all reasons to call the practice. These are uncommon but treatable, and Dr. Viecilli evaluates the same day. Limestone Hills covers any TAD-related emergency at no additional charge for active comprehensive patients.

How Much Do TADs Cost?

TADs are included free when clinically indicated within a comprehensive treatment plan

Standalone or non-comprehensive TADs: $500 per device (placement, monitoring, removal)

The included-when-indicated structure is deliberate. TADs reduce reactive movement, shorten treatment time, and improve outcome predictability. Charging a separate fee for them creates a financial incentive to overuse them or, at the other extreme, to avoid them when they would benefit the case.

Limestone Hills folds TAD placement into the comprehensive treatment fee, so the recommendation is purely clinical rather than financial.

Most PPO orthodontic benefits apply to the comprehensive case the TADs support; medical insurance does not separately cover TADs. Standalone TAD cases (typically when a patient is transferred in from another practice and needs a single anchorage point) are quoted at consultation.

Frequently Asked Questions About TADs

Does TAD placement hurt?

No, not in the sharp-pain sense. Local anesthetic numbs the tissue first, then the screw threads into bone. Patients feel pressure, similar to a filling appointment. Mild soreness for the first 24 to 48 hours after placement is normal and is handled with over-the-counter pain medication.

How long do TADs stay in?

Most TADs remain in place 4 to 8 months. The exact duration matches the planned tooth movement. Removal takes under 5 minutes in-office, often without anesthetic, and the soft tissue heals in a few days.

Are TADs the same as dental implants?

No. Dental implants replace missing teeth and require 3 to 6 months of osseointegration before they can hold force. TADs are smaller, designed for immediate loading the same day or within a week, and intentionally temporary. They are removed once the tooth movement is complete; the bone fills the small channel within weeks.

Will my insurance cover TADs?

When TADs are placed as part of a comprehensive orthodontic treatment plan at Limestone Hills, they are included free of charge, so the insurance question does not apply: the comprehensive case is what is billed and your PPO orthodontic benefit applies to that case. Standalone TAD cases are quoted at consultation; insurance coverage for non-comprehensive TAD work varies by plan.

Why does Dr. Viecilli place TADs in-office instead of referring out?

Two reasons. Logistics: in-office placement removes a second consultation, a second copay, and a 2 to 6 week scheduling delay. Biomechanics: the doctor who designs the orthodontic force system places the screw, so the TAD position is optimized for the planned force vector rather than for surgical convenience.

Position errors at the millimeter level affect outcome, and a single-operator pathway eliminates that handoff risk.
