When recurring dark spots appear in the same areas of your Medit i700 scans, the cause is rarely software-related. In most cases, these fixed defects indicate camera sensor pixel failure. Unlike temporary glitches that disappear after restarting or recalibration, dead pixels are permanent hardware faults requiring professional assessment.&nbsp;The<a href="https://repair.dental/services/intraoral-scanner-repair/medit-intraoral-scanner-repair"> Medit i700</a> relies on high-resolution CMOS camera sensors to capture precise surface data for digital impressions. Each pixel in the sensor detects light independently and converts it into electrical signals for accurate three-dimensional reconstruction. When pixels fail, missing or distorted data points appear, directly impacting scan fidelity and diagnostic accuracy. At Repair. Dental, we use specialized pixel mapping diagnostics to assess sensor health, quantify defect severity, and estimate remaining usable lifespan&mdash;helping practices anticipate when repairs are necessary before image quality becomes clinically unreliablea.

&nbsp;

<h2>How Camera Sensors Work in Medit i700?</h2>

&nbsp;

<h3>CMOS Sensor Architecture</h3>

&nbsp;

The Medit i700 employs a CMOS (Complementary Metal-Oxide-Semiconductor) sensor with a microlens array and RGB color filters. Millions of photodiodes capture light intensity to produce full-color 3D images. Each pixel is manufactured as part of a single silicon unit, making individual pixel repair impossible. Once pixels fail, the entire sensor must be replaced to restore full image quality.

&nbsp;

<h3>Why Pixels Fail?</h3>

&nbsp;

Pixel degradation in the Medit i700 occurs due to thermal stress, repeated power cycles, minor physical impacts, and cumulative electronic radiation. Specific failure patterns include:

&nbsp;

<ul>
	<li>Dead pixels: Permanently inactive, producing dark spots that cluster into larger blind zones.</li>
	<li>Hot pixels: Permanently active, showing bright points that confuse scanning algorithms.</li>
	<li>Stuck pixels: Register fixed intermediate values, appearing as isolated red, green, or blue dots.</li>
</ul>

&nbsp;

High-volume clinical use accelerates these stresses, increasing the risk of pixel failure over time.

<h2>Early Signs of Pixel Failure:</h2>

&nbsp;

<h3>Visual Indicators:</h3>

&nbsp;

Dead pixels manifest as fixed defects in the same image locations, independent of patient or scanning technique. Early failures affecting fewer than ten pixels may go unnoticed but can be revealed by scanning a uniform white surface. Common indicators include:

&nbsp;

<ul>
	<li>Repeated dark spots in identical positions across scans</li>
	<li>Bright points unrelated to tooth morphology</li>
	<li>Isolated colored pixels (red, green, blue)</li>
	<li>Localized scan quality degradation</li>
	<li>Defects worsening after prolonged scanner use</li>
</ul>

&nbsp;

<h3>Controlled Testing Procedures</h3>

&nbsp;

Professional pixel mapping separates true sensor defects from calibration or software issues.

<ul>
	<li>Uniform field testing: Captures images of evenly lit white surfaces. Dead pixels appear as dark points.</li>
	<li>Dark frame testing: Captures images with the lens covered; hot pixels appear as bright points.</li>
</ul>

Differences between two identical Medit i700 units under the same conditions often indicate hardware-specific degradation rather than user error.

&nbsp;

<h3>Pixel Mapping Software</h3>

&nbsp;

Repair.Dental uses advanced software to track pixel behavior across multiple frames, generating detailed defect maps. Reports include:

<ul>
	<li>Total defect counts by type</li>
	<li>Defect distribution patterns</li>
	<li>Severity grading</li>
	<li>Comparison to manufacturer tolerances</li>
	<li>Predicted sensor lifespan</li>
	<li>Repair vs replacement recommendations</li>
</ul>

Dentist Insight: Roughly 25% of scanners reported for &ldquo;poor scan quality&rdquo; have actual pixel failures rather than calibration issues. Clusters of ten or more adjacent dead pixels can disrupt scans even when total counts are below fifty.

&nbsp;

<h2>Repair vs Replace: Making the Right Decision</h2>

&nbsp;

<h3>Professional Sensor Replacement:</h3>

&nbsp;

When pixel mapping confirms failure, <a href="https://repair.dental/services/intraoral-scanner-repair/medit-intraoral-scanner-repair">Medit i700 sensors</a> require full replacement. This involves disassembling the scanner, installing an OEM camera sensor, precise optical alignment, and software recalibration. At Repair. Dental, the process includes:

<ul>
	<li>Free diagnostic pixel mapping and evaluation</li>
	<li>Genuine Medit OEM camera sensor replacement</li>
	<li>Complete optical system recalibration</li>
	<li>Alignment verification and adjustment</li>
	<li>Software configuration and performance testing</li>
	<li>90-day warranty on parts and labor</li>
	<li>Free nationwide shipping both directions</li>
</ul>

Typical turnaround is 2&ndash;3 business days, minimizing disruption for busy practices.

Average Replacement Costs: $600&ndash;$1,400 depending on model and sensor resolution. Scanners with integrated color or NIRI capture typically cost more due to component complexity.

&nbsp;

<h3>Comparing Repair vs Full Scanner Replacement:</h3>

&nbsp;

New Medit i700 scanners cost $30,000&ndash;$45,000, depending on features. A sensor replacement at $1,000 for a 4-year-old scanner extends its lifespan by 3&ndash;4 years. Replacing the scanner introduces additional costs: workflow retraining, staff downtime, and productivity loss.

&nbsp;

When Repair Makes Sense:

<ul>
	<li>Scanner is under 6 years old</li>
	<li>Sensor defect count between 50 and 150 pixels</li>
	<li>Other components function properly</li>
	<li>Practice is satisfied with the current performance</li>
	<li>Repair cost under 5% of replacement</li>
</ul>

&nbsp;

When Full Replacement is Better:

<ul>
	<li>Scanner over 6&ndash;7 years old with heavy use</li>
	<li>Multiple component failures beyond sensor</li>
	<li>Replacement cost approaches $2,000</li>
	<li>Model discontinued or parts scarce</li>
	<li>New technology offers significant clinical advantages</li>
</ul>

Dentist Insight: From a clinical perspective, minor clustered defects can disrupt full-arch scans, making early repair crucial to avoid misdiagnoses or repeated scanning.

&nbsp;

<h2>Preventive Maintenance for Sensor Longevity:</h2>

&nbsp;

Proper handling and environment significantly extend the Medit i700 sensor life.

<ul>
	<li>Maintain storage at 65&ndash;75&deg;F and 30&ndash;50% humidity</li>
	<li>Store in protective cases between patients</li>
	<li>Avoid physical impacts and cable strain</li>
	<li>Perform annual diagnostic pixel mapping</li>
	<li>Apply regular firmware updates</li>
</ul>

Monitoring and Documentation: Establish baseline pixel maps upon acquisition or after sensor replacement. Track degradation trends to schedule proactive maintenance rather than reactive emergency repairs.

Monthly Maintenance Plans at Repair. Dental includes: baseline mapping, predictive replacement scheduling, and guidance on environmental controls.

&nbsp;

<h2>Frequently Asked Questions:</h2>

&nbsp;

Q1: Can individual dead pixels be repaired? 
No. Medit i700 sensors are integrated units. Dead pixels cannot be repaired individually; the sensor must be fully replaced.

Q2: How many dead pixels are acceptable? 
Scattered defects under 25 pixels typically have minimal impact. Clusters exceeding 10 pixels near critical areas or total defects over 50 may require replacement.

Q3: How long do sensors last? 
6&ndash;8 years under optimal conditions. High-volume practices may experience earlier degradation; controlled environments prolong lifespan.

Q4: Does sensor replacement affect scan accuracy? 
Professional replacement restores full accuracy. Pixel mapping before and after service ensures proper calibration.

Q5: Is it safe to continue scanning with minor dead pixels? 
Yes, as long as defects are scattered and not central to occlusal or margin capture. Central cluster defects require immediate attention.
